Question

protons: 8
neutrons: 9
electrons: 10
what is the total charge?

Explanation:

Step1: Determine proton charge

Protons have a charge of +1 each. With 8 protons, the total proton - charge is $8\times( + 1)=+8$.

Step2: Determine neutron charge

Neutrons are neutral, so their total charge is $9\times0 = 0$.

Step3: Determine electron charge

Electrons have a charge of -1 each. 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. Total charge = Proton charge+Neutron charge+Electron charge. So, total charge $=+8 + 0+( - 10)=-2$.

Answer:

-2
