In Lithum 2s electron experience the force of attraction exerted by nucleus
Options:
Answer:
C
Solution:
The 2s electron in Lithium (Li) experiences a net nuclear charge (effective nuclear charge, ) that is less than the actual nuclear charge of +3. This is due to the shielding effect from the inner 1s² electrons, which reduce the attraction between the nucleus and the outer 2s electron.
