How to memorize the periodic table, you have to memorize it quickly

One vertical and one vertical back, as if it were an ancient poem.

Here's how to quickly memorize the periodic table:

1. Remember a few of the most critical points: For junior high school, the most important thing is the H element, 0 element, and C element, basically remember these 3, and the others can be pushed slowly.

2. Distinguish the metal elements: all the metal elements are in the front row, so that we will be easier to remember when we remember further.

3. Recognize the period: In the periodic table, the position in the same horizontal row is called the period, so as to understand it from a comprehensive content.

4. The main family to learn: The same main family is the same in the outermost e-book, and the physical properties are very similar, so it is very easy to remember it with the main family.

5. One back for every 5: hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxyfluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chloride, argon, potassium, calcium. This Huaitan mountain like remembering the first 20 elements is very useful for our periodic table.

6. Each master comes to recite: especially the metal element, sodium metal, you can recite lithium, sodium, potassium, rubidium, cesium. The shapes are very similar and very memorable.

7. Find skills to memorize: For example, hydrogen chlorine, we can consider it as an infringement, so according to our own characteristics, which one of our backs is comfortable, we can recite it in the lead.

Summary of the periodic table of chemical elements.

1. Atomic radius.

1. Except for the first period, the atomic radius of the noble gas element of other periodic elements decreases with the increase of the atomic number;

2 The atomic radius of the elements of the same group increases from top to bottom with the increase of the number of electron layers.

2. The valence of the elements of the discussion hall.

1 In addition to the first period, from left to right in the same period, the highest positive valence of elements increases from alkali metal +1 to +7, the negative valence of non-metallic elements increases from carbon group -4 to -1 fluorine without positive valence, and oxygen without +6 valence, except for the non-positive valence;

2. The highest positive and negative values of elements of the same main family are the same.

3. The melting point of the element.

1. With the increase of atomic number of elements in the same period, the melting point of the elemental metal increases and the melting point of the non-metallic element decreases;

2. From top to bottom of the same group of elements, the melting point of the elemental metal decreases, and the melting point of the non-metallic elemental increases.

4. The metallicity of the elements.

1. The metallicity of elements in the same period decreases from left to right, and the non-metallicity increases;

2. The metallicity of elements in the same main group increases from top to bottom, and the non-metallicity decreases.

5. The most advanced oxide contains the acidity and alkalinity of the slow hidden hydrate.

The stronger the metallicity of the element, the stronger the alkalinity of the hydrate of its most ** oxide; The stronger the non-metallic nature of the element, the more acidic the hydrate of the most ** oxide.

6. Non-metallic gaseous hydrides.

The stronger the element non-metallic, the more stable the gaseous hydride. The stronger the non-metallic nature of the non-metallic elements in the same period, the more acidic the gaseous hydride aqueous solution is. The stronger the non-metallic nature of the non-metallic elements of the same main group, the weaker the acidity of the gaseous hydride aqueous solution.

7. Redox properties of elemental matter.

The stronger the metallicity of the general element, the stronger the reduction of its element, and the weaker the oxidation of oxygen ions of its oxides. The stronger the non-metallic nature of the element, the stronger the oxidation of its elemental substances, and the weaker the reducibility of its simple anions.

How to memorize the periodic table to memorize it relatively quickly, the following are several methods: group memory method, recognition rules, use of memory skills, making memory tools, multiple repetitions, etc.

1. Group memory method: divide the periodic table according to the main groupings, such as alkali metals, alkaline earth metals, transition metals, etc. Start by learning and memorizing the elements and their characteristics in one group, and then gradually expand to other groups.

2. Identification rules: understand some periodic laws in the periodic table, such as the number of periods, atomic number and the change of element properties. This will help you guess where the elements are in the periodic table and quickly memorize some common elements.

3. Use memory skills: Use keywords, images or associations related to the name of the element to aid memory. For example, combine an element's symbol with its name to form an interesting association, or create a simple story about an element's characteristics or purpose.

4. Make memory tools: use colors, charts, ** and other auxiliary tools to visualize the periodic table. You can make your own memory cards, posters, or electronic tools as needed.

5. Repetition many times: Keep in mind the names, symbols, and characteristics of elements by constantly reviewing and repeating your memory. Splitting the time between learning rounds and reviews can help deepen memory.

Application of the periodic table

1. Chemical research: The periodic table is the basic tool for chemical research. It provides the various properties and characteristics of the elements, helping chemists understand the interactions between the elements, the laws of reactions, and the chemical structure.

2. Materials Science: The periodic table is very important for materials science. By studying the properties of elements and combinations of elements, new materials such as alloys, ceramics, semiconductors, etc., can be designed and developed to meet the needs of different fields.

3. Drug research and development: The periodic table is also crucial for drug research and development. Understanding the properties, atomic structure, and electronic configuration of elements can guide drug design and development, helping scientists find molecules with specific functions, such as antibiotics, anticancer drugs, and more.

4. Energy industry: The periodic table plays an important role in the energy industry. For example, it provides a basis for research and development of new energy materials (e.g., solar cells, fuel cells), nuclear energy utilization, and energy storage technologies.

5. Education and popular science: The periodic table plays an important role in education and popular science, helping students and the public to understand the basic knowledge of elements and chemistry. It is widely used in chemistry education and laboratories to provide a foundational framework in the teaching process.

5. Industrial applications: The periodic table also has a wide range of uses in industrial applications. For example, in industries such as metal processing, semiconductor manufacturing, glass production, electronic equipment manufacturing, etc., it is necessary to make a reasonable selection and application of various elements in the periodic table.

The periodic table is as follows:

1. Divide the whole into parts and scatter the memory. Starting from the common element symbols, adopt the strategy of breaking the whole into parts, and consciously memorize them from multiple angles. For example, first memorize the element symbols learned in each lesson, and gradually master the element symbols similar to pinyin in later learning; Sodium (Na), barium (Ba), helium (He), argon (Ar), etc.

2. Easy to mix symbols, contrast memory. For elemental symbols that consist of two letters with the same first uppercase (or second lowercase letter), consider listing them separately to strengthen your memory with contrast.

3. Compile poems, rhyme memory, and the elements required to be memorized and mastered in the first volume of junior high school textbooks include 27 kinds of old talk, including 13 kinds of non-metallic elements and 14 kinds of metallic elements. If these 27 elements and bromine are woven into a rhyme poem, the memory becomes interesting.

4. Give meaning and homophonic memory. That is, the chemical content that needs to be memorized is combined with the homophony in daily life for memory, so that meaningless memory can be transformed into meaningful memory.

Noble gas elements

Noble gases are also known as noble gases, and their chemical properties are very stable and do not easily react with other substances. The stable noble gases are: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (XE), radon (RN), OG).

Keeping in mind the atomic number of a noble gas element, the location of a known atomic number is used to locate an element with a known atomic number by the position of the noble gas. For example, if you want to deduce the position of element 33, because it is between 18 and 36, it must be counted from 36 to the left in the 4th cycle, and it should be in group A.

Generally, only the first 20 are memorized, and the specific order is as follows:Group I: Hydrogen (H), Helium (He), Lithium (Li), Beryllium (BE), Boron (B).

Group II: Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), Neon (Ne).

Group III: Sodium (Na), Magnesium (Mg), Aluminum (Al), Silicon (Si), Phosphorus (P).

Group 4: sulfur (S), chlorine (Cl), argon (Ar), potassium (K), calcium (Ca).

The periodic table of chemical elements is a list of chemical elements sorted from smallest to largest according to their atomic number. The list is generally rectangular in shape, with spaces in the period of some elements, so that elements with similar characteristics are grouped into the same family, such as alkali metal elements, alkaline earth metals, halogen elements, rare gases, etc.

The periodic table of chemical elements is a list of chemical elements sorted from smallest to largest according to their periodic period and relative atomic mass. The list is roughly rectangular, and there are now 118 elements in the periodic table, of which 15 are lanthanides and 15 actinides, each of which is crammed into a single grid, for a total of 60 cells.

Elements with similar characteristics are grouped in the same family, a total of 16 groups, of which there are seven main groups, divided into alkali metals, alkaline earth metals, boron, carbon, nitrogen, oxygen and halogen, and seven sub-families, divided into scandium, titanium, vanadium, chromium, manganese, copper and zinc, an eighth group, and one is the zero group, that is, noble gases.

There is a song about the periodic table of chemical elements on the Internet, which you can look for.
