Before 1500 A.D., other elements were discovered, namely arsenic, antimony, and bismuth. Before 1750, sulfur, cobalt and platinum were discovered.

1. Chemical elements:

A chemical element is a general term for a class of atoms that have the same number of nuclear charges (i.e., the number of protons in the nucleus). From the perspective of Changpei philosophy, it is the result of the qualitative change caused by the quantitative change in the number of electrons of the atom. It refers to more than 100 basic metallic and non-metallic substances in nature, which are composed of only one laughing atom, and each nucleon in its atom has the same number of protons, which cannot be decomposed by ordinary chemical methods, and can constitute all matter.

2. Origin: The origin of the idea of elements is very early, the ancient Babylonians and the ancient Egyptians once regarded water (and later air and earth) as the main elements of the world, forming the theory of three elements. The ancient Indians had four major doctrines, and the ancient Chinese had the Five Elements Doctrine.

The doctrine of the elements, that is, the doctrine of the elements as the simplest constituent parts of all real objects in nature, has arisen since time immemorial. However, in ancient times, the modern notion of elements as a concrete form of matter did not exist. Whether in the ancient philosophy of our country, or in the ancient philosophy of India or the West, the element is regarded as an abstract, a manifestation of the primitive spirit, or the basic nature of matter.

A total of 118 elements have been discovered so far.

History of Elemental Discovery:

No. 1 H hydrogen was discovered in Cavendish in 1766 in Cazhao, England.

No. 2 HE helium was discovered in 1868 by the French astronomer Jean Sun's and the British Lockell using the solar spectrum. In 1895, the British chemist Lemse made it.

No. 3 lithium was discovered in 1817 by the Swede Ja Affostoshi while analyzing hefeldspar.

No. 4 beryllium was discovered in 1798 by Louis Nicolas Walkland, France.

No. 5 B boron was discovered and produced in 1808 by David in England and Guélusak and Tynar in France.

No. 6 c carbon ancient people discovered.

In 1772, nitrogen was discovered at the same time in Schoeller, Sweden and Rutherford, Denmark, and was later confirmed by Lavoisier of France as a neo-primitarian caller.

No. 8 O Oxygen was discovered in 1771 by Priestley in England and Schoeller in Sweden.

No. 9 F fluorine was predicted by chemists in 1786 and confirmed by the French chemist Moissant in 1886 by using fluorine gas by electrolysis.

No. 10 neon was discovered in 1898 by British chemists Lemse and Rayleigh.

No. 11 sodium Na was discovered and prepared by electrolysis by the British chemist David in 1807.

As of September 30, 2022, there were 118.

First cycle: 2, 2nd cycle: 8, 3rd cycle:

8, 4th cycle: 18, 5th cycle: 18, 6th cycle:

32, 7th Cycle Chang Mark: 32. There are 118 elements in the periodic table of the yuanzhongqin.

The periodic table is resistant to cultivation and has 7 periods and 16 groups. Each horizontal row is called a cycle, and each vertical row is called a family (group VIII contains three columns). These 7 cycles can be divided into short cycles and long cycles).

There are 16 families, one in each column from left to right (except for VIII). For example: hydrogen belongs to group IA elements, while helium belongs to group 0 elements.

Element position inference.

1. The number of elemental periods is equal to the number of electron layers outside the nucleus.

2. The ordinal number of the main group elements is equal to the number of outermost electrons.

3. To determine the number of families, we should first determine whether it is the main family or the secondary family, and the method is to use the atomic number to gradually subtract the number of elements in each period, which can be determined by the final difference. In the first to fifth periods, when the difference is less than or equal to 10, the difference is the family ordinal, when the difference is , it is the family, and when the difference is greater than 10, then subtract 10, and the final result is the family ordinal.

In the section. The difference between the six and seven cycles is 1: group a, and the difference is 2:

A group, the difference is 3 17: lanthanide or actinides, the difference is between 18 and 21: minus 14, the difference is 22 24:

Family, the difference is greater than 25: minus 24, which is the corresponding main family.

As of 2021, there are 118 known chemical elements, of which 92 are naturally occurring, and the other 26 are synthetic. These elements are classified into a row or column of the periodic schedule of different elements according to their chemical properties and atomic structure.
