B. Anions have more electrons than protons, giving them a negative charge.
and
D. Cations have more protons than electrons, giving them a positive charge.
Explanation:
Anions have negative charge because electrons give negative charges. On the other hand, cations have positive charges because protons have a positive charge and they have more protons.
B. Anions have more electrons than protons, giving them a negative charge.
D. Cations have more protons than electrons, giving them a positive charge.
Explanation - Ions are the result of atoms or molecules that lose or gain electrons. If an atom or a molecule is positively charged then it is called as cation and if it has negative charge then it is called as anion.
Cations have positive charge because the atom has lost its electron while anions have negative charge because the atom has gained the electron. The number of protons is more than the electron in cations and less in anions.
Vacuoles are fluid-filled organelles used mainly as storage compartments. Depending on the cell type, they can hold things like enzymes, waste, food, and water.
