Question

Electro valency of non-metal atom is maximum in
1. Sodium hydride
2. Calcium carbide
3. Magnesium oxide
4. Aluminium nitride
please its urgent
i will give u more than 5 points ​

Answer 1

Answer:

A) Sodium hydride, NaH ⟹Na

+

+H

−

, electrovalency of Na is +1.

B) Calcium carbide, CaC

2

, electrovalency of Ca is +2.

C) Magnesium oxide, MgO, electrovalency of Mg is +2.

D) Aluminium flouride, AlF

3

, electrovalency of Al is +3.

So, electrovalency of metal is maximum in AlF

3

.

Answer 2

$Answer \:$

1) Sodium hydride,NaH => (Na+)+(H-),

electrovalency of Na is +1.

B) Calcium carbide, CaC2, electrovalency of Ca is +2.

C) Magnesium oxide, MgO, electrovalency of Mg is +2.

D) Aluminium flouride, AlF3, electrovalency of Al is +3.

So, electrovalency of metal is maximum in AlF

3

Therefore, The answer is option number (d)
