Lightning protection! Okay, now it's going to take 8 minutes, and you've memorized the periodic table, don't you believe it? Then you use the remaining 2 minutes to compare:
First Cycle: Hydrogen Helium - Invasion.
Second cycle: lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon -- carp skin holding carbon eggs to raise blessing milk.
Third Cycle: Sodium, Magnesium, Aluminum, Silicon, Phosphorus, Sulfur, Chlorine, Argon -- That beautiful Guilin has green teeth.
Fourth Cycle: Potassium, Calcium, Scandium, Titanium, Vanadium, Chromium, Manganese -- Marry Kangtai Counter-Revolutionary.
Iron, cobalt, nickel, copper, zinc, gallium, germanium -- Tiegu pinched the newlyweds.
Arsenic, selenium, bromine, krypton -- angry shock.
Fifth cycle: rubidium, strontium, yttrium, zirconium, niobium -- so to you.
Molybdenum, technetium, ruthenium -- terrible.
Rhodium, palladium, silver, cadmium, indium, tin, antimony--Daddy Silver Brother Insiti.
Tellurium, iodine, xenon -- location immortals.
Sixth cycle: cesium, barium, lanthanum, hafnium, --color) color shell (shell), blue (color) river.

Iridium, platinum, gold, mercury, lead--a white towel for it to pull.
Bismuth, polonium, astatine, radon -- will not love winter (day).
Seventh cycle: francium, radium, actinium -- lightning protection!
Alas, there is no way, such a difficult thing to remember, and you have to memorize it, so it can only be like this. The above is horizontal by cycle back. Below is the vertical press on the family back:
Hydrogen, lithium, sodium, potassium, rubidium, cesium, francium, please Li Na to join the private interview (When will Li Na become the emperor) Beryllium, magnesium, calcium, strontium, barium, radium, comparable to Gates, tired (heh!)

<> chemical elements must be back 20, which are hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chloride, argon, potassium and calcium. A chemical element is a general term for a class of atoms that have the same number of nuclear charges (protons in the nucleus). From a philosophical point of view, an element is the result of a quantitative change in the number of protons of an atom that leads to a qualitative change.
Common elements are hydrogen, nitrogen, and carbon, among others. As of 2019, a total of 118 elements have been discovered, 94 of which are found on Earth. The nuclei of the elements with atomic number 83 (bismuth element and later) are unstable and decay.
The 43rd and 61st elements (technetium and promethium) have no stable isotopes and decay. The heaviest surviving element in nature is neptunium 93.

Chemical element refers to more than 100 basic metal and non-metal substances in nature, which are composed of only one kind of 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 substances. Some examples of common elements are hydrogen, nitrogen, and carbon.
As of 2012, a total of 118 elements have been discovered, 94 of which are found on Earth. Elements with atomic numbers greater than 83 (i.e., after bismuth) are unstable and will undergo radiative decay. The 43rd and 61st elements, i.e., technetium and promethium, have no stable isotopes and undergo decay.
However, even elements with atomic numbers as high as 95 and no stable nuclei can be found in nature, which is the natural decay of uranium and thorium.

Hello! The quiet road suddenly became lively, like a boiling hot pot.
When in doubt, please ask.

I think it's easier to memorize the periodic table and the corresponding element symbols in Chinese first, and then memorize them in English. That's how I learned professional English.
First of all, you have to know how to read the periodic table, if you memorize them one by one according to the numbers or according to the song of the periodic table, it will be too difficult.
First memorize the elements of the main family, and the main family should be vertically memorized, memorize the Chinese name and then memorize the element symbols. The first ten elements of the subgroup are scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, and zinc. The other sub-family elements are vertically backed, and there are only three elements in each group, which is easy to remember.
That's how I memorized it, and in this way, each set of elements had a great similarity in nature.
I think it may take a bit of effort to match the element symbol with the Chinese name, because for the Chinese, chemistry is really a foreign product, and the symbol and the name are not very related. But if you use English, it's much easier to remember, and there are only about seven or eight elements in nearly 120 elements The symbols are not abbreviations in English, they are from Latin, but I believe you should also have some knowledge of Latin, after all, you are abroad, and the language environment is good. If you can memorize these abbreviated elemental symbols, you can almost know the full name.
See it a few more times and remember it.
I'm sure you're okay, it's just a periodic table
However, I wrote down the entire table after learning the properties of each element......Still hope it helps.

I don't know what grade you are a student, generally in junior high school, as long as you know the first 20 elements, in high school, with the increase of knowledge, there will be more elements involved in the questions, such as some metal elements, iron, manganese, as well as alkali metals, halogens, oxygen, nitrogen, carbon and other elements, I hope it will help you.

A chemical element is a general term for a class of atoms that have the same number of nuclear charges (the number of protons in the nucleus). From a philosophical point of view, elements are the result of a qualitative change caused by a quantitative change in the number of electrons in an atom. [1] >>>More
The Si chemical element is silicon.
Silicon (silicon) is a chemical element, the chemical symbol is SI, formerly known as silicon. Atomic number 14, relative to the atomic mass, there are two allotropes of amorphous silicon and crystalline silicon, which belong to the third period on the periodic table, the metalloids of group IVA. Silicon is also an extremely common element, yet it is rarely found in nature in its elemental form. >>>More
The code for zinc is 30 and the code for lead is 82. Zinc is a chemical element, its chemical symbol is Zn, its atomic number is 30, and it is located in the 4th period, group b in the periodic table of chemical elements. Zinc is a light gray transition metal and is also the fourth"Common"of metal. >>>More
It feels like everything is made up of small elements, and I can write it in chemical formulas.
The chemical element symbol of tungsten is W, the atomic number is 74, the relative atomic mass is, the atomic radius is 137 picometers, and the density is grams per cubic centimeter, which belongs to the VIB group of the sixth (second longest) period in the periodic table. Tungsten is mainly a hexavalent cation in nature, and its ionic radius is. Due to the small radius of W6+ ions, high electricity price, strong polarization ability, and easy to form complex anions, tungsten is mainly in the form of complex anions [WO4]2-, which combines with cations such as Fe2+, Mn2+, and Ca2+ in solution to form wolframite or scheelite precipitation. >>>More
