question 14 (1 point)
anions are best described as
ions with more protons than neutrons
ions with more electrons than protons
isotopes with more neutrons than protons
atoms with the same number of protons and electrons
question 15 (1 point)
protons are found in the nucleus of an atom. they
have a neutral charge.
form cations.
have a positive charge.
have a negative charge.

Explanation:

Question 14

Anions are negatively - charged ions. Since protons have a positive charge (\(+1\)) and electrons have a negative charge (\(- 1\)), for an anion to have a negative charge, the number of electrons (\(e^-\)) must be greater than the number of protons (\(p^+\)). That is, if \(n(e^-)>n(p^+)\), the overall charge \(Q=n(p^+)\times(+ 1)+n(e^-)\times(-1)<0\).

Protons are sub - atomic particles located in the nucleus of an atom. By definition, protons have a positive charge (\(+1\) elementary charge). Neutrons have a neutral charge, and electrons have a negative charge. Cations are positively - charged ions formed when an atom loses electrons, but protons themselves do not form cations in the sense of being the sole entity forming them (cations are usually whole atoms or groups of atoms with a net positive charge due to electron loss).

Answer:

ions with more electrons than protons
