Answer 2

Explanation:

ionisation of chlorine is less as compared to potassium. chlorine is more neare r to 18 th group that's why it's ionisation energy less . valency of chlorine is -1 because it is 17 the group that means group number-18 17-18=-1. potassium is 1 group so valency is +1. metals mean s block means 1 group and 2 group so potassium has more metallic chracter compared to potassium. electronegativity is more for chlorine because it is a non metal and less for potassium because it is metal
