Classify each statement about effective nuclear charge, Zeff, astrue or false.
-Effective nuclear charge increases from left to right across aperiod on the periodic table
-Across a period, as Zeff increases, atomic size increases
-in a N atom, a 1s electron has a great Zeff than a 2selectron
-Effective nuclear charge does not depend on the number ofelectrons present in an atom
-Electrons in a s orbital are more effective than those in otherorbitals at shielding other electrons from the nuclear charge
-a 1s electron in a B atom has a smaller Zeff than a 1s electron ina Be atom
