Question

In which case effective nuclear charge is minimum
(a)Be
(b)Be
(c) Be
(d) All have the same effective nuclear charge​

Answer 1

Answer:

d option is the answer of this question

Answer 2

Answer:

When +ve charge increases the no. of e decreases hence less no. of e will shield the valence e so effective nuclear charge will increase and size decreases. Hence effective nuclear charge is less in Be2+ and more in Be3+.
