Question

explain pentration effect​

Answer 1

$\mathbb{\huge{\pink{ANSWER}}}$

Power means the ability of an orbital to attract an electron. This process is accompanied with release of energy. The Penetration effect of s orbital is the maximum because of the closeness to the nucleus than are the p, d and f orbitals.

Answer 2

penetration effect is one of the factors which affect the ionisation energy of an atom

for example in the orbitals 4s,4p,4d,4f

the 4s orbital need more energy to remove an electron than 4pand other orbitals because each orbital has different piercing power

hence this is known as penetration effect of orbitals.
