Question

Why isn’t there anyone helping for chemistry I need this by literally tomorrow morning before 8:30 ;-;

4.) Draw XY3 where X has 5 valence electrons and Y has 7 valence electrons
5.) Draw AB2 where A has 2 valence electrons and B has 7 valence electrons.

Answer 1

See image

Explanation:

The valence electrons (outer shell electrons) get shared between the first and second element in the compound the purpose is for both the elements to get to the stable state by having the outer shell filled up to 8 electrons. See image.
