Base your answer on the information below and on your knowledge of chemistry. the radius of a lithium atom is 130 picometers, and the radius of a fluorine atom is 60 picometers. the radius of a lithium ion, li+, is 59 picometers, and the radius of a fluoride ion, f–, is 133 picometers. explain, in terms of subatomic particles, why the radius of a lithium ion is smaller than the radius of a lithium atom.

Because the attraction force of the protons is higher in the ion.

Explanation:

The atom is composed of nuclei with protons (positively charged) and neutrons (with no charge) and by an electrosphere with electrons (negatively charged). Because of the opposite charges, the protons and electrons are attracted by an electrostatic force.

The electroshpere is formed by levels, and as far from the nuclei is the electrons, as weak is the electrostatic force. When an atom loses one electron, it comes from the last level of the electrosphere, thus, the electrons that remain will be closer to the nuclei, and there'll be more protons than electrons, so the electrostatic force will be greater, and the electrons intends to approximate of the nuclei. Thus, the radius is smaller.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.
