Answer 2

The formula of the compound is A2B5.?The number of electrons in the outermost orbit of A and B are?

Answer :- 5&6

Explanation:-

=>It can also be written as A+5B-2

so, A have 5 electrons in the outermost shell.

and B shows oxidation state of -2

=>So its outer most shell has 8-2 i.e 6 electrons.

So, the number of electrons in the outermost orbit of A and B are 5&6
