Question

protons: neutrons: electrons: what is the total charge? 0

Explanation:

Step1: Determine charge of protons

Protons have a charge of +1 each. There are 2 protons, so total proton - charge is $2\times(+ 1)=+2$.

Step2: Determine charge of neutrons

Neutrons have a charge of 0. There is 1 neutron, so total neutron - charge is $1\times0 = 0$.

Step3: Determine charge of electrons

Electrons have a charge of -1 each. There are 2 electrons, so total electron - charge is $2\times(-1)=-2$.

Step4: Calculate total charge

Total charge = Proton charge+Neutron charge + Electron charge. So, $+2 + 0+( - 2)=0$.

Answer:

0
