Aluminium Sulfide
According to rules the positive specie is named first and the negative specie is named last.
8S or S8 but it is not 8S8
8S8 does not make senes
Beside, is this element is existed.
It means that u have 64 molecules of Sulphur.
Elements of Group 1 and group 2 in the periodic
table contain elements so reactive that they are never found in the free state
<u>Explanation</u>:
The metals in group 1 of periodic table consisting of 'alkali metals' which include lithium, potassium, sodium, rubidium, Francium and caesium. They are highly reactive because they have low ionisation energy and larger radius. The group 2 metals consist of 'alkaline earth metals' which include calcium, strontium, barium, beryllium, radium and magnesium. These alkaline earth metal have +2 oxidation number, hence are highly reactive.
These both group metals are mostly reactive and so are never found in a free state. When they are exposed to air they would immediately react with oxygen. Hence, are stored in oils to avoid oxidation.
0.381 meters
1inch= 0.0254 meter
0.0254 x15=0.381
True, it would slow down.
