Periodic table of chemical elements.

The arrangement is as follows:

1. The right decreases in turn, and increases from top to bottom.

2. The periodic table has 7 periods and 16 families. 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).

3. In the same period, from left to right, the number of electrons outside the nucleus of the element is the same, the number of electrons in the outermost shell increases in turn, and the atomic radius decreases (except for group zero elements). The ability to lose electrons is gradually weakened, the ability to gain electrons is gradually increased, the metallicity is gradually weakened, and the non-metallic ability is gradually enhanced.

4. In the same family, from top to bottom, the number of electrons in the outermost shell is the same, the number of electrons outside the nucleus gradually increases, the atomic radius increases, the atomic number increases, the metallicity of the element increases, and the non-metallicity decreases.

The periodic table of chemical elements is based on atomic weight.

A list of chemical elements sorted from small to large. The list is usually rectangular with spaces in some element loops, so elements with similar characteristics can be grouped into the same family, such as alkali metal elements.

Alkaline earth metals, halogen elements.

Noble gases, non-metals, transition elements.

Wait. This makes the periodic table form elemental divisions, which can be divided into seven main families, 7 auxiliary households, households, and 0 households. Due to its ability to accurately characterize various elements and their relationships, the periodic table is widely used in chemistry and other scientific fields as a very useful framework for analyzing chemical behavior.

1) Arrange them in the order of atomic number!

2) The number of electron layers is the same for one period!

3) The outermost shell has the same number of electrons and similar chemical properties in a longitudinal row!

In the periodic table, the horizontal arrangement is arranged in order according to the number of nuclear charges, ending with group 0 elements, which is called the Zhoulianghu period, and there are currently 7 cycles.

The longitudinal is the various Shengzheng family, the valence electron configuration is the same, and the properties are very similar.

The following are the first 20 elements, 1 to 20 in order from left to right:

H hydrogen, HE, helium, Li, beryllium, B boron. C carbon, N nitrogen, o oxygen, f fluorine, ne neon.

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, and halogen group elements.

Noble gases, etc.

The periodic table of chemical elements is based on the period of the elements and the relative atomic mass.

A list of chemical elements sorted from smallest to largest. The list is roughly rectangular, and there are now 118 elements in the periodic table, among which the lanthanides are the ones.

and actinides 15 each, each squeezed into a single grid, for a total of 60 grids.

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.

-The electronic layout of the No. 18 shirt element is as follows.

The electronic configuration of element -24 is as follows.

The electronic configuration of element -30 is as follows.

The electronic configuration or clever burial of element No. 36 is as follows.

Layout rules:Construction principle: the lower the energy of the whole system, the better. In general, the newly filled electrons are filled in the empty orbital with the lowest energy.

Hinder's rule: Electrons occupy as many orbits as possible and spin in the same direction.

Pauli's incompatibility principle: In the same system, no four quantum numbers with two electrons are exactly the same.

Energy level staggering: A phenomenon in which the energy of some orbitals with a large number of electron layers is lower than the energy of some orbitals with a smaller number of electron layers.
