The greatest effective nuclear charge in a many-electron atom is experienced by an electron in a ________ subshell.
Given:
The objective is to fill the blanks
The greatest effective nuclear charge in a many-electron atom is experienced by an electron in a ________ subshell.
The effective nuclear charge is the attractive force which is experienced by the outer electron from the nucleus ,which would be lesser than actual nuclear charge due to the
shielding of inner electrons .This is the reason there is more inner shells are there, and whereas the effective nuclear charge will be less. Thus electrons in inner subshell experience higher effective nuclear charge than that of the outer electrons. Thus 2s subshell experiences greatest effective nuclear charge ,since the nucleus is shielded by 1s orbital only.
