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. True False Within a family, elements with higher atomic numbers have atoms of larger radius because the atoms have lower effective nuclear charge. True False Within a period, elements with lower atomic numbers have lower electronegativity because the valance electrons are in higher principal energy levels. True False Within a family, elements with lower atomic...

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...

Question 3 (3 points) One part of Dalton's Atomic Theory states: Elements are composed of small, indivisible, indestructible particles called atoms. Is this statement true or false, and why? O True, because atoms are the smallest piece of an element. True, because atoms are cannot be broken into smaller pieces. O True, because atoms are like tiny billiard balls. O False, because atoms are destroyed during chemical reactions. O False, because electrons can be removed from atoms.

Classify each statement about
penetration and shielding as true or false. Assume all lower-energy
orbitals are fully occupied.
Classify each statement about penetration and shielding as true or false. Assume all lower-energy orbitals are fully occupied True False Answer Bank An electron in an orbital that penetrates closer to the nucleus will always experience more shielding than an electron in an orbital that does not penetrate as far. An electron in a 2s orbital penetrates into the region occupied by...
