Answer Bank 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 Zeff than a 2s electron. A 1s electron in a Be atom has a smaller Zeg than a 1s 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.

Some patterns of electron configuration are listed below. In each case, [G] stands for a noble-gas core and n, m, or o stand for integer numbers like 1, 2, 3 and so on. Note: assume G is lighter than Rn. Think about the chemical elements made of atoms with an electron configuration that matches each pattern. In what block or blocks of the Periodic Table would these elements lie? Would they be metals, nonmetals, metalloids, some of each?

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…

The Aufbau Principle describes the order of subshells in an atom in terms of energy. Higher numbered shells have higher energy. It is complicated by occasional overlapping. The specific order of subshells using the Aufbau Principle can be found using the diagonal arrow diagram found in Chapter 8, and this is the same order found on the periodic table. What is the order of subshells in period 2 ? 2s ____ What is the order of subshells in period 3 ? 3s ____ What is the order of subshells in period 4 ? 4s ____ ____ What is the order of subshells in period 5 ? 5s ____ ____
