The periodic table is back 20, and the periodic table is back to me

Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon -- Carp Skin Holding Carbon Eggs and Milk Third Cycle: Sodium, Magnesium, Aluminum, Silicon, Phosphorus and Sulfur, Chloride, Argon -- The Beautiful Guilin Leaves Green Teeth (That Beautiful Ghost Reveals Green Teeth) The Fourth Cycle: Potassium, Calcium, Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, Zinc, Gallium, Germanium, Iron Gu Pinching Pain Newlyweds, Arsenic, Selenium, Bromine, Krypton -- Angry Shock Fifth Cycle:

Individuals have a vertical back, and only 1-20 elements are required to carry a horizontal back. This allows you to use elements of the same family or period to extrapolate unknown elements.

Monovalent potassium chloride, sodium silver, divalent oxygen, calcium, barium, magnesium, zinc, trialuminum, tetrasilicon, pentavalent phosphorus, ditriiron, ditetracarbon, 1-5valent have nitrogen, copper, mercury, bivalent is the most common, positive copper, hydrogen potassium, sodium silver, n-dicopper, magnesium, calcium, barium, zinc, 3-aluminum, 4-silicon, 46-sulfur, 245-nitrogen, 3-5 phosphorus, 157, chloro-23-iron, 2467, manganese is positive, carbon has positive 4 and positive 2.

How to memorize the periodic table of chemical elements is as follows:

1.Monovalent hydrochloride, potassium, sodium silver, divalent oxygen, calcium, barium, magnesium, zinc, trialuminum, tetrasilicon, pentavalent phosphorus, ditriiron, ditetracarbon, nitrogen from one to five valents, copper and mercury bivalent are the most common.

2.Gen Yun Qin memorizes according to the structure of the periodic table. Three short, three long and one unfinished, eighteen high and late longitudinal sixteen clans, seven main clans, seven deputy clans, and one zero clan and eight clans.

It means that there are seven cycles in the periodic table, three of which are long and three short, and an incomplete cycle has eighteen longitudinal rows, which are sixteen families, of which seven are major, seven are subordinate, one is zero, and one is eight.

3.Positive copper, potassium, potassium, sodium, silver, copper, magnesium, calcium, barium zinc. 3. Aluminum, 4 silicon, 46 sulfur, 245 nitrogen, 35 phosphorus.

157 chlorine 23 ferric, 2467 manganese is positive. Carbon has positive four and positive two, and then keep the negative price in mind. Negative iodine bromo, fluorochlorine, negative dioxysulfur, phosphorus triazonide.

You can choose to memorize it in a way that you can understand.

Introduction to the periodic table of chemical elements:

The periodic table of chemical elements is arranged in order from smallest to largest atomic number. Some periods have spaces that allow elements with similar properties to be grouped into the same group, such as alkali metals, alkaline earth metals, and halogens and rare gases. As a result, the elements formed in the periodic table are divided into seven main families, seven secondary families, and so on.
