An element belongs to group II. What would be its valency? Write the formula of molecules of compounds it
will form with elements in VA VIA and VIIA groups​

Answer 1

Answer:

1.valency of group II is 2

2.Formula of compound with group VA is M3X2

3.Formula of compound with group VIA is MX

4.Formula of compound with group VIIA is MX2

Explanation:

1.Because they contain 2 valence electron

2.Because valency of group VA is 3

3. Because valency of group VIA is 2

4.Because valency of group VI is 1
