I hope it will be helpful to my classmates

Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Sodium, Magnesium, Aluminum, Silicon, Phosphorus, Sulfur, Chlorine, Argon, Potassium, Calcium, Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, Zinc, Gallium, Germanium, Arsenic, Selenium, Bromine, Krypton, Rubidium, Rutonium, Rutonium, Palladium, 118 metallic elements, non-metallic elements, and rare gas elements such as cadmium, indium, tin, antimony, and iodine. Chemical elements refer to more than 100 basic metallic and non-metallic 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.

1.Hydrogen (qīng) h
Hydrogen [hydrogen], metallic hydrogen [hydrogenium]. Gas element symbol. Colorless, odorless and tasteless. is the lightest of the elements. It is very versatile in industry.
1h [protium]. There is a proton in the nucleus, which is the main component of hydrogen, and the common hydrogen contains the cocoon.
d or 2h deuterium. There is a proton and a neutron in the nucleus, and the deuterium contained in ordinary hydrogen. It is used in thermonuclear reactions.
T or 3h tritium [tritium]. There is one proton and two neutrons in the nucleus. Radioactive.
2.Helium (hài)he
Helium. Gas element symbol. It is colorless, odorless and tasteless, with very little content in the atmosphere and extremely inactive chemical properties.
It is used to fill light bulbs and neon tubes, and is also used to make styrofoam. Helium in liquid form is often used as a refrigerant.
3.lithium (lǐ)li
Lithium. Metallic element symbol. Silvery-white, easy to oxidize and turn black in the air, soft, is the lightest of the metals.
Chemically reactive; It is used in the atomic energy industry and metallurgical industry, and is also used to make special alloys, special glass, etc.
4.Beryllium (pí) be
Beryllium [beryllium]. Metallic element symbol. Off-white, hard and light. Used in the atomic energy industry, beryllium aluminum alloy is used.
Airplanes, rockets, etc.
5.Boron (péng) (5).
Boron [boron]. Metallic element symbol. Black or silvery-gray solid. The crystal boron is black, with a melting point of about 2300 °C, a boiling point of 3658 °C, and a density of gram cm3; The hardness is second only to diamond, which is brittle.
6.Carbon ( tàn) c (6).
Carbon [carbonium]. Carbon is a non-metallic element. Carbon is a very common element that is widely found in the atmosphere and crust in many forms. Carbon has long been recognized and utilized, and a series of carbon compounds, organic matter, are the foundation of life.
7.nitrogen (dàn)n (7).
Nitrogen [nitrogen]. Gas element symbol. The name of the element is in Greek, which originally meant "saltpeter".
It was discovered in 1772 by the Swedish pharmacist Scherer and the English chemist Rutherford, and later determined by the French scientist Lavoisier that it was an element. The content of nitrogen in the earth's crust is that most of the nitrogen in nature exists in the atmosphere in the form of elemental molecular nitrogen, which accounts for 78% of the volume of air. The most important mineral of nitrogen is nitrate.
There are two naturally occurring isotopes of nitrogen: nitrogen 14 and nitrogen 15, where nitrogen 14 is abundant as.
8.oxygen (yǎng)o
Oxygenium. Gaseous elements. The old translation is 氱.
The Greek word means "acid", and the name was given by the French chemist Lavoisier because Lavoisier mistakenly believed that all acids contained this new gas. Until 2013, the name for oxygen in Japanese was still "acid". The Taiwanese language was influenced by the Japanese occupation period in Taiwan, and it is also called oxygen by the Japanese pronunciation of "acid".

The 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, halogen elements, rare gases, etc.
The periodic table has 7 periods and 16 families. Each row is called a cycle, and each row is called a family (VIII B group consists of 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 B).

This should be done according to your personal situation, depending on whether you are calling more or being called more, if you are called more, you can handle the call lump sum, the caller can handle the local call monthly, the caller can also handle the long-distance package tariff, but the tariff standards in each region are different, depending on which region you are in, it is recommended that you can go to the local business hall to consult the current local tariff. But in general, Unicom's tariff is still cheaper than that of mobile, about 15% lower!
