Identify the charge on the following atom

• Positive Charge (cation)

• Negative Charge (anion)

• Neutral Charge

Answer explanation

To find a change on an atom you are looking at the electrons (- charge) and the protons (+ charge).

If you have more electrons than protons it would be a positive charge.

If you have more electrons than protons it would be a negative charge.

If you have the same amount of protons and electrons the atom will be neutral.

Identify the following atom as neutral, a cation (positive charge or an anion (negative charge)

8 Protons, 6 electrons, 8 neutrons

• Positive Charge (cation)

• Negative Charge (anion)

• Neutral Charge

Answer explanation

This atom has more protons than electrons so it will have a positive charge

Identify the following atom as neutral, a cation (positive charge or an anion (negative charge)

8 protons, 10 electrons, 8 neutrons

• Positive Charge (cation)

• Negative Charge (anion)

• Neutral charge

Answer explanation

The atom would have a negative charge because it has more electrons which are a negative particle than protons which is a positive charge.

What's the charge on the following atom?

• -2

• +2

• -4

• +4

Answer explanation

To find the change you count how many electrons (-) you have and then you subtract from how many protons (+) you have

4 electrons - 2 protons = -2.

It's a negative because electrons have a negative charge and you have more electrons than protons.
