What best describes a cation and anion?

• A cation has more protons than electrons, giving it a net positive charge. An anion has more electrons than protons, consequently giving it a net negative charge.

• A cation has more electrons than protons, giving it a net negative charge. An anion has more electrons than protons, consequently giving it a net positive charge.

• A cation has more protons than electrons, giving it a net positive charge. An anion has more protons than electrons, consequently giving it a net positive charge.

• A cation has more protons than electrons, giving it a net positive charge. An anion has more electrons than protons, consequently giving it a net positive charge.
