Question

Sodium atom, Na forms the positive ion Na+, but chlorine atom CI, does not form the
positive CI+ ion.



​

Answer 1

Since ionization potential increases across a period, the ionization potential of Na is much smaller than that of Cl. Hence, Na can lose an electron to form Na+ ion whereas Cl cannot lose an electron to form Cl+ ion.

Answer 2

Answer:

Since ionization potential increases across a period, the ionization potential of Na is much smaller than that of Cl. Hence, Na can lose an electron to form Na+ ion whereas Cl cannot lose an electron to form Cl+ ion.
