Question

Magnesium is considered as element while magnesium sulphide is considered as a compound. Give reason *​

Answer 1

Answer:

Magnesium Sulphide is a simple inorganic compound made up of magnesium and sulphide. The magnesium sulphide formula or formula for magnesium sulfide is given as MgS. It is the chemical formula of magnesium sulphide and one of the best uses to understand its physical importance is the determination of the molecular weight of the compound. The molecular weight of the compound as determined by the magnesium sulphide formula or the formula for magnesium sulfide is 56.38 g/mol. Another interesting property that can be understood by looking at the magnesium sulfide formula is the electron exchange between the two elements. It is clear from the magnesium sulfide formula that magnesium and sulphur form the compound in a 1:1 ratio, hence the two electrons donated by magnesium are taken up by sulphur atoms in maintaining a neutral charge.

Answer 2

Reason is as follows -

1. Element is defined as the entity that has particular type of atom. The atom of that particular element will contain same amount of protons.
2. On the other hand, compound is defined as entity formed by combination of two or more elements of different types.
3. Magnesium has specific type of atom in it so it is an element. Magnesium sulphide has different type of elements in it namely Magnesium, Sulphur and Oxygen, thus it is a compound.
