What is the difference between an element and an atom? Difference Between Element and Atom

Element is a general term for a class of atoms with the same proton number, such as an atom with a proton number of 1 is called hydrogen. These atoms with a proton number of 8 are called oxygen. It doesn't matter if it's charged or not, and it doesn't matter how many neutrons you have, as long as the number of protons in the atoms is the same, it's the same element.

Atoms, on the other hand, are concrete particles that make up an element. Without atoms, there are no elements.

Element is a general term for atoms, which belongs to the macroscopic concept, which is used to describe macroscopic substances and is described by types, not numbers.

For example, water (H2O) is a substance composed of two elements, hydrogen and oxygen, and it cannot be said that there are two elements.

Atoms are microscopic particles that exist objectively. It is used in the constitution of microscopic particle molecules. That is, the type, and the number.

For example, water molecules are made up of two atoms, hydrogen and oxygen.

A water molecule is made up of two hydrogen atoms and one oxygen atom. The front and back should correspond to each other.

In short: when it comes to matter--- answer what elements are --- --- composed of.

When it comes to molecules--- it must be said that atoms are --- species or --- composition.

Elements are a macroscopic big concept, and we just say that a substance is made up of several elements. Atoms are microscopic concepts, and a molecule is made up of atoms.

The element includes its elemental and ionic states. Atoms are just elemental substances.

The difference between an element and an atom is as follows:

1. Concept: An element is a general term for the same class of atoms with the same number of nuclear charges. Atoms are the smallest particles in chemical change.

2. Quantity meaning: the element focuses on the type and does not indicate the number, and there is no meaning of the quantity; Atoms represent both types and numbers, and have the meaning of quantity.

3. Field of use: Elements are used to describe the macroscopic composition (customarily speaking) of matter. For example, water contains hydrogen and oxygen, and water is composed of hydrogen and oxygen. But it cannot be said that "water is composed of two elements of hydrogen and one element of oxygen".

Atoms are used to describe the microscopic composition (conventionally speaking) of matter, for example, a water molecule is made up of two hydrogen atoms and one oxygen atom. But it cannot be said that "a water molecule is made up of hydrogen and oxygen." ”

4. Connection: Element is a general term for the same class of atoms; Atoms are the basic units that make up an element.

Atom:

Atom refers to the basic particles that are inseparable from a chemical reaction, and atoms are inseparable in a chemical reaction. But in the physical state it can be divided (only discovered in the late 19th and early 20th centuries). Therefore, although the atom is already small, it is still not the most basic unit that makes up the world.

An atom is the smallest unit in which an element retains its chemical properties.

The atom itself also has an internal structure, which is made up of protons, neutrons, and electrons. Elements are closely related to atoms, which are the most basic building blocks of chemical substances, and an element is actually a substance that contains only one class of atoms. Therefore, to make a new element means to make a new atom.

An element generally refers to a chemical element, which is a general term for a class of atoms with the same number of nuclear charges (the number of protons in the nucleus). From a philosophical point of view, an element is the result of a qualitative change caused by a quantitative change in the number of protons of an atom. Some examples of common elements are hydrogen, nitrogen, and carbon.

Atoms refer to the basic particles that are inseparable from chemical reactions. Atoms are inseparable in chemical reactions but can be divided in the physical state. An atom is made up of a nucleus and electrons that move around the nucleus.

Atoms make up the smallest unit of matter in general, known as elements. There are 118 known elements and hence have a nuclear structure.

Atoms are the smallest particles that make up matter. No, atoms can be divided into nuclei and extranuclear electrons, which in turn are composed of protons and neutrons, and the number of protons is the basis for distinguishing various different elements. So far, the process of understanding chemical elements has not ended.

At present, the research on molecular structure in chemistry and nuclear particles in physics are being carried out in depth, and it is expected that it will bring new understanding of chemical elements. As of 2007, a total of 118 elements have been discovered, 94 of which are found on Earth.

(Atoms are the smallest particles in chemical change, but instead of simple, indivisible solid spheres, they are made up of a positively charged nucleus at the center of the atom and negatively charged electrons outside the nucleus.) ）

An element is a general term for a class of atoms with the same number of nuclear charges (i.e., the number of protons in the nucleus). For example, oxygen molecules and water molecules both contain oxygen atoms, and their nuclear charge numbers are both 8, that is, they both contain 8 protons in the box, so they are collectively called oxygen elements.

A molecule is the smallest particle that maintains the chemical properties of a substance. Molecules can be redivided.

Atoms are the smallest particles in chemical change. Atoms can combine with each other to form molecules. Atoms can no longer be divided.

The difference between an element and an atom is:

1) Elements only talk about types, not numbers;Atoms talk about both types and numbers.

2) Elements belong to macroscopic concepts;Atoms are microscopic concepts.

3) Elements for the macroscopic composition of matter;The microscopic composition of matter is made up of molecules (molecules are made up of atoms), atoms and ions, and never elements.

4) Elements are abstract concepts, and only through atoms can ions embody their concrete meaning;Atoms often illustrate the microscopic nature.

5) In the chemical change, the type and quality of the element remain unchanged, reflecting the macroscopic significanceIn chemical changes, the type of atoms, the number of atoms, and the mass of atoms remain unchanged, reflecting the microscopic essence.

6) The meaning of the element is inseparable from the atom, the relative unity of macroscopic and microscopic, large and small. For example, the metallicity of an element refers to the ability of the atoms of an element to lose electrons, and the non-metallicity of an element refers to the ability of the atoms of an element to gain electrons.

Characteristics of the atom:

1) Atoms are very small in mass and size, which is very similar to molecules.

2) Atoms are always in motionSame with molecules.

3) There are gaps between atoms. and molecule-like.

4) An atom is a kind of particle that makes up matter.

5) Atoms are not redivided in chemical changes, but only recombined.
