Question

Give the example of
1. Trivalent electropositive ion
2. Trivalent electronegative ion
3. Divalent electropositive ion

Answer 1

Answer:

1 Aluminum

2 Nitrogen

3 SO4

Answer 2

1) Aluminium

2) Nitride

3) Magnesium

Explanation:

1. Trivalent electropositive ion

A trivalent electropositive ion means having the valency of plus three. Aluminium atom loses three electrons from its outermost (valence) shell to form trivalent positive ion.

2. Trivalent electronegative ion

A trivalent electronegative ion means having the valency of minus three. Nitride (N^-3) ions can attract three electrons to its outermost shell to form trivalent negative ion.

3. Divalent electropositive ion

A divalent electropositive ion means having the valency of plus two. Magnesium atom loses two electrons from its outermost (valence) shell to form divalent positive ion.
