Question 2

Shielding effect is only exerted by inner shell electrons.

True

False

Question 3

Shielding effect is equivalent to repulsion between the electrons in the atom/ion.

True

False

Question 4

Interelectronic repulsion refers to the repulsion between electrons in the same orbital.

True

False

Question 5

O: 1s22s22p4
