protons: 7\nneutrons: 7\nelectrons: 10\nwhat is the total charge?

Explanation:

Step1: Determine proton charge

Protons have a charge of +1. With 7 protons, the total proton - charge is $7\times( + 1)=+7$.

Step2: Determine neutron charge

Neutrons are neutral, so the total neutron - charge is $7\times0 = 0$.

Step3: Determine electron charge

Electrons have a charge of -1. With 10 electrons, the total electron - charge is $10\times(-1)=-10$.

Step4: Calculate total charge

Add up the charges from protons, neutrons, and electrons. The total charge $Q$ is $Q=(+7)+0+( - 10)=-3$.
