How many electrons does lithium chloride have

Properties:

In its pure state, lithium is a silvery, shiny metal that rapidly tarnishes in air to form lithium nitride. It is the first element in the group of alkali metals. It is the lightest of almost all elements and even floats on oil. It is the hardest of all alkali metals, but is still easy to cut with a knife.

Lithium is a very base metal that is extremely reactive chemically. It combines with most of the elements of the PSE, generating a lot of heat. It burns in oxygen at around 100 ° C with an intense red light to form lithium oxide. Lithium forms lithium hydride with hydrogen in a warm atmosphere. It reacts with molecular nitrogen even at room temperature, similar to magnesium. This is why one speaks of the so-called oblique relationship between the alkali metals and the alkaline earth metals.

When the lithium comes into contact with water, it reacts with the water, producing a lot of hydrogen. However, this does not ignite. Lithium hydroxide is also formed.

2 Li + 2 H2O → 2 LiOH + H2

A total of 2 modifications of lithium are known. Below -196 °, face-centered cubic lithium changes into body-centered cubic lithium.
