Solution

The correct statement about a positive ion is: "It has more protons than electrons".

Here's why:

  1. An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

  2. A positive ion, also known as a cation, is formed by the loss of one or more electrons.

  3. Therefore, a positive ion has more protons (which are positively charged) than electrons (which are negatively charged), giving it a net positive charge.

The other statements are incorrect because:

  • "It has more electrons than protons" would describe a negative ion, not a positive ion.
  • "It has more electrons than neutrons" is not necessarily true for any specific ion, as the number of neutrons does not directly affect charge.
  • "It has an equal number of protons and electrons" would describe a neutral atom, not an ion.
