Answer:
Electrons are far apart from the nucleus as we move down the group.
Explanation:
The ionization energy is the amount of energy which is necessary to remove an electron from an atom.
In an atom there exist a force of attraction at the center (nucleus). This is because of the positive charge which exists in the nucleus. This force of attraction is less felt as the distance between the electron and the proton increases. Hence the ionization energy increases as the number of shells increases for an atom. As we move down the group in the periodic table, the number of shells increases which implies a decrease in ionization energy.
Covalent bonds formed when two atoms share an electron, as opposed to an Ionic bond where one atom takes an electron(or two) from another atom.
B. False
Stability is determined by the ratio of neutrons and protons. Electrons are not in nucleus.
