Question

multiple - choice question
what is this atoms charge, and why?
0, because it has an equal number of protons and electrons
-1, because it has two electrons and only one proton
+1, because it has two electrons and only one proton
-2, because it has two electrons
rewatch

Explanation:

Protons have a charge of +1 and electrons have a charge of - 1. Neutrons are neutral. In the atom shown, there is 1 proton and 2 electrons. The net charge is calculated as the sum of the charges of its sub - atomic particles. So, \(+1+( - 1)+( - 1)=-1\).

Answer:

-1, because it has two electrons and only one proton
