Answer

Explanation:

Step1: Recall charge - calculation formula

The charge of an atom is calculated as Charge = Number of protons - Number of electrons.

Step2: Calculate charge for Atom 1

For Atom 1, Number of protons = 9, Number of electrons = 9. Charge = 9 - 9 = 0.

Step3: Calculate charge for Atom 2

For Atom 2, Number of protons = 9, Number of electrons = 8. Charge = 9 - 8 = + 1.

Step4: Calculate charge for Atom 3

For Atom 3, Number of protons = 9, Number of electrons = 10. Charge = 9 - 10=-1.

Step5: Calculate charge for Atom 4

For Atom 4, Number of protons = 9, Number of electrons = 9. Charge = 9 - 9 = 0.
