Classify each statement about effective nuclear charge, Zeff, as true or false. True Across a period, as Zeff increases, atomic size increases. Answer Bank Electrons in an s orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge. A ls electron in a Be atom has a smaller Zer than a 1s electron in a Li atom. Effective nuclear charge does not depend on the number of electrons present in an atom. Effective nuclear charge increases from left to right across a period on the periodic table. In a Be atom, a 1s electron has a greater Zer than a 2s electron. MacBook Pro False

How many electrons in an atom could have these sets of quantum numbers? n = 3 electrons n = 5, € = 1 electrons n = 7,€ = 3, me = -1 electrons
Each of the statements below attempts to explain why some periodic property varies predictably among elements in the periodic table. Determine if each statement is true or false. Within a period, elements with higher atomic numbers have atoms of smaller radius because the valance electrons are in higher principal energy levels. Within a family, elements with higher atomic numbers have lower ionization energy because the valance electrons are in higher principal energy levels. Within a period, elements with higher atomic numbers have higher ionization energy because the valance electrons are in higher principal energy levels. Within a family, elements with higher atomic numbers have higher electronegativity because the atoms have higher effective nuclear charge. Within a period, elements with lower atomic numbers require more energy to remove an electron from the atom, because the valance electrons are in higher principal energy levels. Within a period, elements with lower atomic…
