    Physical Properties:1Silvery-white metal. 2。Soft. 3。It is less dense than water and can float on the surface of the water. 4。Melting point bottom, less than 100 degrees. 5。It can conduct electricity and heat.

    Sodium metal is soft and can be cut with a knife. After cutting the outer skin, sodium can be seen to have a silvery-white metallic luster. Sodium is a good conductor of heat and electricity. The density of sodium is, less dense than water, the melting point of sodium is, and the boiling point is.

    Chemical properties of sodium.

    The outermost shell of the sodium atom has only 1 electron and is easily lost. Therefore, the chemical properties of sodium are very reactive, which are mainly manifested in:

    1.Reaction of sodium with oxygen.

    Observe the demonstration experiment: sodium reacts with oxygen.

    At room temperature 4NaO2 2Na2O

    At the time of ignition 2na o2na2o2 (pale yellow).

    sodium peroxide).

    Sodium peroxide is more stable than sodium oxide.

    2.Sodium reacts with non-metals such as sulfur.

    In addition to being directly combined with Cl2, sodium can also be directly combined with many other non-metals, such as sulfide.

    2na+s=na2s

    Sodium sulfide) 3.Sodium reacts with water.

    Observe the demo experiment:

    Sodium reacts with water.

    2na+2h2o=2naoh+h2↑

    The chemical properties of sodium are very reactive, so it cannot exist in a free state in nature, therefore, sodium is usually stored in kerosene in the laboratory.

    Sodium metal conducts electricity because it is a metal.

    Not an electrolyte, the electrolyte must be a compound.

    The electrolyte solution conducts electricity by relying on free-moving ions. Conducts electricity during the directional movement of anions and cations in the electrolyte solution.

    Metallic conductors conduct electricity, and the classical conductivity theory holds that it is due to the presence of a large number of free electrons that can move freely inside the metal conductor, and these free electrons move directionally under the action of the electric field force to form an electric current.

    1: The conduction of electrolytes is accompanied by chemical reactions. Because the ion must finally gain electrons at the cathode, and must lose electrons at the anode to form a pathway, otherwise it can only form a potential difference and cannot form a continuous current, and the metal conduction is not accompanied by a chemical reaction.

    2: The conduction of the electrolyte is the movement of charged ions in the electrolyte to produce an electric current, while the conductivity of a metal is the movement of electrons to produce an electric current (the essence is the overall shift of the electrons).

    Remember to give satisfactory answers!

    Metallic conduction is the directional movement of free electrons.

    The electrolyte solution conducts electricity and is an anion and ion.

    of directional movements.

    1. Principle of metal conductivity:

    1) Electron gas theory: due to the small number of electrons in the outermost shell of a metal atom, it is easy to lose electrons and become metal ions, and the valence electrons shed by the metal.

    Almost evenly distributed.

    In the whole crystal, it acts like an "electronic gas" that spreads throughout the whole piece of metal, thus holding all the metal atoms together. These electrons are also known as free electrons.

    2) In metal crystals, the movement of free electrons does not have a certain direction, but under the condition of an external electric field, the directional movement of free electrons forms an electric current, so the metal is easy to conduct electricity. Different metals have different electrical conductivity.

    The three metals with the strongest electrical conductivity are: Ag, Cu, and Al

    2. Principle of conductivity of electrolyte solution:

    1) The electrolyte ionizes anions in solution.

    and cations, the wires put in are regarded as two poles, the anode connected with the positive electrode of the power supply is called the anode, and the negative electrode connected to the power supply is called the cathode, after the power is energized, the cation moves to the cathode, the anion moves to the anode, and the anion and ion move directionally to conduct electricity.

    And at the same time, along with the electrolysis process of the electrolyte solution, an oxidation reaction occurs on the anode.

    A reduction reaction takes place on the cathode.

    2) Factors affecting the conductivity of electrolyte solutions:

    a. When other conditions are the same, the concentration of ions in the electrolyte solution and the charge of the ions, the higher the total concentration of the ions, the more charge they carry, and the stronger the conductivity.

    b. Temperature: Generally speaking, when the electrolyte solution increases the temperature, the conductivity is enhanced, because the temperature is high and the ion movement rate is large, among which the weak electrolyte solution such as acetic acid.

    The change in solution is particularly noticeable.

    The way in which an electrolyte conducts electricity is not the same as that of a metal conductor. In a metallic conductor, the current is transported by the movement of free electrons, and in the electrolyte, it is by charged ions. In the electrolyte, because the charges of positive and negative ions are equal, they are not electrically electric, and we call them electroneutral.

    When we apply voltage to the electrolyte, the ions run towards the electrode opposite to their own polarity due to the attraction of a strong electric field. The cations run to the cathode, and the anions run to the anode. Their movement allows an electric current to pass through, which is how electrolytes conduct electricity.

    The conduction of metals is the electrons inside the metal, and the electrons inside the metal are free.

    Electrolyte conductivity is the directional migration of charged ions in a solution in an electric field.

    So the essence is different.

    But electric current is the flow of electrons.

    Sodium metal is a very reactive metal that reacts violently when exposed to liquids such as air and water, so extra care is required when handling sodium metal in the laboratory.

    However, there are liquids that can come into contact with sodium metal without an immediate and violent reaction and are also able to form an oxide film on the surface of sodium metal, slowing down the reaction rate of sodium metal with its surroundings, including:

    Liquid ammonia: Liquid ammonia has a high dielectric constant at room temperature, which can slow down the reaction rate of sodium metal with the surrounding environment. In addition, liquid ammonia can also form a solution with sodium metal, which conducts electricity, so safety measures need to be taken when handling sodium metal in liquid ammonia.

    Petroleum ether: Petroleum ether is a colorless, volatile organic liquid that can come into contact with sodium metal without immediate reaction. In addition, petroleum ethers can also form an oxide film on the surface of sodium metal, thereby slowing down the reaction rate of sodium metal with the surrounding environment.

    Cyclohexane: Cyclohexane is a colorless, volatile organic liquid that can also come into contact with sodium metal without immediate reaction. Similar to petroleum ethers, cyclohexane is also able to form an oxide film on the surface of sodium metal, thereby slowing down the reaction rate of sodium metal with the surrounding environment.

    It is important to note that although these liquids do not react violently immediately, proper safety measures need to be taken when handling sodium metal to avoid accidents.

    Sodium metal conducts electricity in its liquid state and is very conductive. Since liquid sodium metal surfaces react with oxygen in the air, they need to be stored and used under an inert gas. Protected by an inert sodium gas, such as bonded hail argon, liquid sodium metal can be non-reactive with many liquids and still conduct electricity.

    For example, liquid sodium metal can conduct electricity without reacting with inert gases such as liquid helium, liquid nitrogen, and liquid hydrogen.

    Sodium metal is in solid form at room temperature and pressure, and it reacts with many liquids such as water, acids, etc., when it is in its liquid state. However, if the liquid sodium is placed in a non-polar liquid reflux, such as petroleum ether, toluene, etc., it can be observed that the sodium metal does not react and still has electrical conductivity. This is because the interaction force between the non-polar liquid and the sodium metal is small, and it cannot provide enough activation energy to cause the sodium metal to react.

    To find a liquid that does not react with sodium metal and at the same time has conductive properties, ionic liquids can be considered. Ionic liquids are a class of organic salts with low melting points (usually below 100 degrees Celsius). They are electrically conductive** to the ions in them and do not react chemically when in contact with sodium metal.

    Some common ionic liquids include:

    1-Butyl-3-methylimidazole salt (e.g., 1-butyl-3-methylimidazole bromide or 1-butyl-atop-3-methylimidazole fluoroborate).

    1-ethyl-3-methylimidazole salt (e.g., 1-ethyl-3-methylimidazole bromide salt or 1-ethyl-3-methylimidazole fluoroborate).

    1-Hexyl-3-methylimidazole salt (e.g., 1-hexanoslowyl-3-methylnacolumidazole bromide or 1-hexyl-3-methylimidazole fluoroborate).

    Ionic liquids have many advantages, such as high electrical conductivity, low vapor pressure, good thermal stability, and compatibility. However, they are costly and may not be suitable for all applications. In practice, make sure to follow safety protocols, as ionic liquids can be corrosive and toxic.

    Sodium metal is an extremely reactive metal, which is easy to react with most liquids and gases at room temperature and pressure, and even causes combustion or **. Therefore, sodium metal needs to be stored and handled in an environment of inert gas or inert liquid to avoid flushing reaction with other substances.

    In terms of liquids, the slag can be judged to consider the use of some inert liquids, such as liquid nitrogen, liquid argon, etc. These inert liquids do not react with sodium metal on their own, and sodium metal can be cooled to a lower temperature to slow its activity and reduce safety risks. At the same time, these inert liquids also have some electrical conductivity, so they can separate the space between the liquid and the sodium metal, and maintain their separator potential within a certain range.

    However, even when separated by an inert liquid, sodium metal will constantly react with oxygen, water vapor, and other substances at the liquid interface, releasing a large amount of hydrogen and potentially generating heat during the reaction, so it is still necessary to pay close attention to safety.
