Answer 1

Explanation:

1)group element have a common policy of one and developy of oxygen into and the satisfied the combining capacity of oxygen elements of which group are required does the oxygen oxide of the first group element have the common formula of m2O eg Na²O, K²O, etc

2) of groups 13 elements in 1 and the velocity of oxygen into 2 and the satisfied the combining capacity of crop 13 elements 3 of halogens are required dusty molecular formula will be of form XMX³ eg Alcl3,Bf3,etcetc
