普里莫·莱维《元素周期表》中第一个故事《氩》英文版 | The First Story “Argon” in “Periodic Table” by Primo Levi There are the so-called inert gases in the air we breathe. They bear curious Greek names of erudite derivation which mean “the New,”“the Hidden,”“the Inactive,” and...
Hydrogen is the first element in the periodic table. It is a colorless, odorless, and tasteless gas. Hydrogen is the lightest element with an atomic number of 1. Hydrogen has many important properties. It is highly flammable and can react explosively with oxygen. However, when burned in air...
The elements are arranged in vertical groups that contain elements that have similar chemical and physical properties. The first group of elements of the periodic table is is made up from the most reactive metals. They have a variety of uses, for example lithium is used to manufacture laptop, ...
Hydrogen is the first element on the periodic table. It is a very light gas with unique properties. Hydrogen has a low density and is colorless, odorless, and tasteless. It is highly flammable and can react explosively with oxygen. Hydrogen has many important uses. It is used as a fuel ...
