How to write the symbols of all chemical elements

Look at the periodic table. Encyclopedia.

Chemical element symbols are unique symbols used to mark elements, and common chemical element symbols include hydrogen H, helium HE, lithium Li, beryllium BE, boron B, carbon C, nitrogen N, oxygen O, fluorine F, neon Ne, sodium Na, magnesium MG, aluminum Al, silicon Si, phosphorus P, sulfur S, chlorine Cl, argon Ar, potassium K, calcium Ca, etc.

Element symbols are usually represented by the first letter of the Latin name of the element, such as carbon-c. If the first letter of several element names is the same, add another letter in the element name after the first letter to distinguish it, such as chlorine-cl.

Significance of chemical elements

Chemical symbols and their rules of use are the unique language of chemistry, and are an important tool for chemical science to study the composition, structure and change of substances, and are the basis for us to learn chemistry.

to correctly express the chemical process and the composition, structure and change laws of its substances, and cultivate students' logical thinking ability. Element symbols, molecular formulas, and chemical equations are typical structural forms of chemical terms, and the syllabus clearly states that students should be able to write, read, and use them, and understand their chemical meanings.

That is, to understand, to know, to be right. In order to overcome these cognitive difficulties, it is necessary for students to first understand the meaning of the symbols in the teaching process.

Element symbols (symbolsforelements) are unique symbols used to mark elementsIt can also represent an atom of this element, and most solid elements are also represented by element symbols.

Element symbols are usually represented by the first letter (uppercase) of the Latin name of an element, such as carbon-c. If the first letter of several element names is the same, add another letter (must be lowercase) in the element name after the first letter (it must be uppercase) to distinguish it, such as chlorine-cl.

Elements 1-5.

1. Hydrogen, H, the element that forms water, is composed of the Greek ydor (meaning water, which evolved into Latin is hydra) and gennao (I produce).

2. Helium, he, this is the element found in the solar spectrum, so it is named after the Greek word helios (sun).

3. Lithium, li, is named because it is found in leaf stone, and the Greek word lithos means stone.

4. Beryllium, BE, is named because it was found in emeralds (beryl).

5. Boron, b, got its name from borax, the Latin word for borax is boron because it can melt metal, and the Arabic word boron means welding.

Elements 6-10

6. Carbon, c, has been discovered since ancient times, and is named after carbon (carbon).

7. Nitrogen, n, the element that forms saltpeter, is named after the Greek word nitron (meaning saltpeter, which evolved into the Latin word nitre), and the suffix -gen see hydrogen (1).

8. Oxygen, o, that is, the element that forms acid, Greek oxys (acid), the suffix -gen see hydrogen (1).

9. Fluorine, F, named after fluorite (Latin fluor, original meaning flux), chemical composition is calcium fluoride.

10. Neon, neon, comes from the Greek neon (new).

Elements 11-15.

11. Sodium, Na, English for sodium, is named after the preparation of electrolytic soda (soda, the chemical composition is sodium carbonate). The Latin word natrium also means soda.

12. Magnesium, MG, named after the bitter soil (magnesia, a place in Greece that is rich in bitter soil).

13. Aluminum, AL, named after alum (Latin alumen, the original meaning is alum, which is astringent), and the chemical composition is potassium aluminum sulfate.

14. Silicon, Si, named after quartz glass (silex).

15. Phosphorus, p, named because it emits cold light, is composed of the Greek phos (light) and phoros (bring).

Isotopes:

Subsequently, in early 1921, the British physicist Aston proved that most chemical elements have different isotopes. The atomic weight of an element is the average of the isotopic mass as the fraction of the mass of the isotope present in nature.

During the same period, in 1913, the British physicist Moselle systematically studied the wavelength of X-rays obtained by cathodes made of various elements, and pointed out that the characteristics of an element are the nuclear charge number of the atom of this element, that is, the atomic number determined later.

Thus, it is obviously unreasonable to think of isotopes as several different individual elements. Because the characteristic of the atom that determines an element is not the atomic weight, but its nuclear charge number.

20 Chemical Element Symbols:Hydrogen, helium, lithium, beryllium, boron (H, He, Li, Be, B).

Significance. Chemical symbols and their rules of use are the unique language of chemistry, and are an important tool for chemical science to study the composition, structure and change of substances, and are the basis for us to learn chemistry.

Element symbols, molecular formulas, chemical equations.

are the typical structural forms of chemical terms, and they are taught in the syllabus.

It is clearly stated: "Students should be able to write, read, and use, and understand their chemical significance." That is, to understand, to know, to be right.

In order to overcome these cognitive difficulties, in the teaching process, students must first understand the meaning of the element symbols, and then deepen their understanding in the teaching of material molecular formulas and chemical equations, so as to form a standardized and fixed chemical language, and use this chemical language to correctly represent and study various chemical changes.

Chemical element symbols are usually represented by the first letter (uppercase) of the Latin name of the element. If the first letter of several element names is the same, add another letter (must be lowercase) in the element name after the first letter (must be uppercase) to distinguish them.

Chemical symbols refer to the symbols used to represent various elements, all material compositions except mixtures, and their atomic numbers in chemistry, and can be applied to various reaction formulas. Chemical symbols have undergone different evolutions in different regions, and finally in 1841, chemical symbols with universal use were formed, and they are still used today.

The symbols of chemical elements are equivalent to the letters of English and Russian, with 26 letters in English and 33 letters in Russian, while there are currently more than 100 symbols of chemical elements.

The symbol of a chemical element is usually represented by the first letter (uppercase) of the Latin name of the element, however, some elements have the same first letter of the name by just following the first letter (which must be uppercase) with a lowercase letter, which is the second letter of the Latin name of this element, such as fe is iron and cu is copper. If the first and second letters of the element's name are the same, use the third letter as a lowercase letter, e.g. as is arsenic, ag is silver, and ar is argon.

New elements are constantly appearing, and people have to create their own Latin names for new elements, to define their symbols.

The chemical element symbol also denotes one atom or one mole of this element in addition to the element, such as the chemical element symbol ca stands for the element calcium, one calcium atom or one mole of calcium atom (40 grams of metallic calcium). To represent several atoms of this element, a coefficient can be added in front of the symbol of the chemical element.
