The periodic table of elements is the most important part of chemical knowledge. It was invented by the Russian chemist Mendeleev in 1869. If you want to learn chemistry well, you must first understand the periodic table of chemistry and the relationship between the elements.

periodic table of elementsIntroduction to the periodic table of elements

The periodic table of chemical elements is a list of chemical elements ordered from smallest to largest atomic number. The list is roughly rectangular, with spaces left in the periods of some elements so that elements with similar properties can be grouped into the same group, such as halogens, alkali metal elements, rare gases (noble gases or noble gases), radioactive elements, etc. This makes the elements in the periodic table divided into seven main groups, seven sub-groups, zero groups, and eight groups. Because the periodic table accurately predicts the properties of various elements and their relationships, it is widely used in chemistry and other sciences as a useful framework for analyzing chemical behavior.

Cycle 1: Hydrogen Helium ---- Violation

Second cycle: lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon ---- carp skin holding carbon egg nourishing milk

The third cycle: sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon ---- That beauty in Guilin has green teeth

Fourth cycle: Potassium Calcium Scandium Titanium Vanadium Chromium Manganese ---- Marry Kangtai Counterrevolutionary

Iron, cobalt, nickel, copper, zinc, gallium and germanium ---- Tiegu pinches the newlyweds

Arsenic Selenium Bromine Krypton ---- Anger Shock

The fifth cycle: rubidium, strontium, yttrium, zirconium, niobium ---- so I tell you

Molybdenum Technetium Ruthenium ---- Incredible

Rhodium, palladium, silver, cadmium, indium, tin and antimony ---- Dad Yin Ge Yin Xiti

Tellurium Iodine Xenon ---- Location Fairy

The sixth cycle: cesium barium lanthanum hafnium ---- (color) color shell (shell) blue (color) river

Tantalum tungsten rhenium osmium ---- But (see) the crow (crow) (attract) the geese

Iridium, platinum, mercury, weight, lead ---- a white towel for it to hold

Bismuth, polonium, astatine, radon ---- I don’t like winter (weather)

The seventh cycle: francium, radium, actinium ---- lightning protection!
