mate I have typed only half the ques. the full ques is as follows :

An atom X has electronic configuration 2, 8, 7. It combines with y having 1 electron in its outermost shell. (a) what type of bond will formed between x and y ( b) write the formula of the compound formed.

ANSWER:

X 2,8,7

2,8,7So , it is a non-metal with valency 1 .

2,8,7So , it is a non-metal with valency 1 .Y .,1

.,1So , it is a metal with valency 1.

The type of bond that will form between X and Y is the IONIC BOND since one is metal and non-metal.
