Question

How does the tendency of the elements to lose electrons change in the Modern Periodic Table in (i) a group, (ii) a period and why?

Answer 1

1) in a group the elements will have same valance electrons but different number of shells.
2)in a period the elements will have same number of shells but different number of valence electrons.
the tendency of losing electrons does not depend on group or period.

Answer 2

Answer:

(ii) Tendency to lose electrons will decrease along the period due to increasing valence electrons.

(i) Moving down the group, the tendency of loose electrons will increase as electrons lie farther from the nucleus.
