Question

a 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:

KLM

286

(a) Since, it has 6 valence electrons, it belongs to group no. 16.

(b) It has 3 Valence shells, so it belongs to period no 3.

(c) The number of valence electron is 6.

(d) The valency of E is 2 because it requires 2 electrons to achieve its stability .

(e) It is a non-metal.

Answer 2

The correct answer is (c) non-metal x has 2 electrons more than neutral atom.

• Since X loses two electrons, its valence becomes +2 and it frames the particle of the structure X2+

• Likewise, the valency of Y is - 1, and its ionic structure is Y−.
• Development of compound with X and Y:
• Since the compound is framed by particles I am ionic. Ionic mixtures are High dissolving focuses, are solvent in fluid arrangements due to versatile particles, and are solvent in water.
• This electron trade brings about an electrostatic fascination between the two particles called an ionic bond.
• A particle that loses at least one valence electron to turn into a decidedly charged particle is known as a cation, while an iota that acquires electrons and turns out to be adversely charged is known as an anion.
