Classify each statement about effective nuclear charge, Zeff, as true or false. True False Effective nuclear charge does not depend on the number of electrons present in an atom. A 1s electron in a Be atom has a smaller 4 than a Is electron in a Li atom.Across a period, as Zeff increases, atomic size increases. 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. In a N atom, a Is electron has a greater Zeff than a 2s electron.
