Question

a lithium atom has three protons, three neutrons, and three electrons. what is the overall charge on this atom? -3 0 +1 +3

Explanation:

Step1: Determine the charge of protons

Protons have a charge of \(+1\) each. There are 3 protons, so total charge from protons is \(3\times(+1)= + 3\).

Step2: Determine the charge of electrons

Electrons have a charge of \(-1\) each. There are 3 electrons, so total charge from electrons is \(3\times(-1)=-3\).

Step3: Determine the charge of neutrons

Neutrons have a charge of \(0\).

Step4: Calculate the overall charge

Overall charge \(=\) charge from protons \(+\) charge from electrons \(+\) charge from neutrons. So, \(+3+(-3)+0 = 0\).

Answer:

0
