Question

Non-metal X gain 2 electrons then (a) Non-metal X has 2 neutrons less than neutral atom (b) Non-metal X has 2 protons more than neutral atom (c) Non-metal X has 2 electrons more than neutral atom (d) Non-metal X has 2 protons less than neutral atom​

Answer 1

Answer:

Since X loses two electrons, its valence becomes +2 and it forms the ion of the form X

2+

. Similarly, valency of Y is -1 and is ionic form is Y

−

.

Formation of compound with X and Y:

Since compound is formed by ions i is ionic. Ionic compounds are High melting points, are soluble in aqueous solutions because of mobile ions and are soluble in water.
