Electrons in an s orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge. Effective nuclear charge increases from left to right across a period on the periodic table. Across a period, as Z increases, atomic size increases, Effective nuclear charge does not depend on the number of electrons present in an atom. In a N atom, a ls clectron has a greater Za than a 2s electron. Als electron in a B atom has a smaller Z than a ls election in a lB
