cations are formed when a neutral element ___________ valance electrons giving the atom an overall positive charge because there are more protons than electrons.

• loses

• gains

What would the correct charge of magnesium (Mg) when it forms a cation?

• Mg⁺

• Mg²⁺

• Mg³⁺

• Mg⁸⁺

What is the charge of an Ion that has 46 protons and 48 electrons

• +2

• -2

Answer explanation

The difference between protons and electrons determines the charge.

Example: if there is 1 proton and 2 electrons, then the difference is 1.

Since electrons outweigh protons then it is a negative charge.

Which of the following are examples of anions?

• K⁺

• S^-2

• Cl^-

• Mg⁺²

What type of atom is this?

• Neutral atom

• Cation

• Anion
