b. why do ionic compound conduct electricity in molten or aqueous state?
c. why is chloride Ion stable?

​

Answer 1

lower the ionization potential of the non metallic element

Answer 2

Answer:

Explanation:

(i) The modern periodic law states that "The properties of elements are the periodic functions of their atomic number."

(ii) Henry Moseley put forward the modern periodic law.

(iii) Modern Periodic table has 7 periods and 18 groups.
