multiple - choice question\nwhat is the charge of this atom?\nprotons\nneutrons\nelectrons

Explanation:

Step1: Recall charge of sub - atomic particles

Protons have a charge of + 1, neutrons have a charge of 0, and electrons have a charge of - 1.

Step2: Count sub - atomic particles

There are 2 protons, 1 neutron and 2 electrons.

Step3: Calculate the net charge

Net charge= (Number of protons×Charge of proton)+(Number of neutrons×Charge of neutron)+(Number of electrons×Charge of electron) = (2×1)+(1×0)+(2×(- 1))=2 + 0-2=0.

Answer:
