State true or false for the following: 1.Within a period, elements with higher atomic numbers require more energy to remove an electron from the atom, because the atoms have higher effective nuclear charge. 2.Within a family, elements with higher atomic numbers require more energy to remove an electron from the atom, because the valance electrons are in lower principal energy levels.3. Within a family, elements with lower atomic numbers have higher electronegativity because the atoms have higher effective nuclear charge.

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 family, elements with higher atomic numbers require more energy to remove an electron from the atom, because the atoms have higher effective nuclear charge. Within a period, elements with lower atomic numbers have atoms of larger radius because the valance electrons are in higher principal energy levels. Within a period,...

answer a b or c
Why is the atomic radius of magnesium ion much smaller than that of a neutral charged magnesium atom? (See the atomic radius graph) The magnesium ion's electrons require less space. No electrons are lost, they move to unoccupied spaces about the nucleus. The magnesium ion has fewer principle quantum energy levels, this causes a decrease in atomic radius. The magnesium ion has a higher Z-effective nuclear charge. The magnesium ion has more principle quantum energy...

Classify each statement about effective nuclear charge, Zeff, as true or false. True False Effective nuclear charge is dependent on the number of electrons present in an atom. In a N atom, a ls electron has a greater Zer than a 2s electron. Electrons in a p orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge. Als electron in a B atom has a smaller Zeff than a ls electron in a...
