Classify each statement about effective nuclear charge, Zeff, as true or false

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.
