Select the larger:
Both of these species have 5 protons, but B also has 5 electrons where B+3 has only 2 electrons. Since there are more electrons fighting for the same nuclear charge in neutral B, then neutral B will be larger.
Both of these species have 9 protons, but F also has 9 electrons where F- has 10 electrons. Since there are more electrons fighting for the same nuclear charge in F-, then F- will be larger.
Both of these species have 2 electrons, but He also has 2 protons where B+3 has 5 protons. Since there are more protons (nuclear charge) pulling the electrons closer in B+3, that ion is smaller and He is larger.
2)
