X is lithium - atomic no. 3
Y is Florine - atomic no. 9
a) li3fl.
b) this will be ionic bond.
c) sorry I can't gave structure here but now you can try.

Given X (Group 1) & (Period 2) so X is lithium(Li)
Y(Group 17)& (Period 2) so Y is Fluorine(F)
(a) So the formula of the compound formed by X & Y is LiF
(b)The compound LiF is ionic because Fluorine(F) is electronegative.And we know that when a electronegative atom present the compound is ionic.
(c)Here is the electron dot structure of the LiF compound
