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.

    Part A Why do atomic radii decrease from left to right across a period of the periodic tablo? O Atomic radii decrease from left to right across a period because the total number of electrons on the electron shell decreases. O Atomic radii decrease from left to right across a period because the effective nuclear charge increases. O Atomic radii decrease from left to right across a period because the effective nuclear charge decreases O Atomic radii decrease from left...

  • answer a b or c Why is the atomic radius of magnesium ion much smaller than...

    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...

    Which of these elements would have the highest number of valence electrons? Phosphorus Beryllium Bromine Sulfur Which of these elements requires the highest amount of energy to remove a valence electron resulting in the formation of a cation? Boron Carbon Oxygen Sodium Atomic radius increases down a group (family) because: There are less and less protons in an atom. There are more and more electrons in an atom and electrons take space. There are less and less electrons in an...
