In the atomic structure model, the negatively charged particles in the orbitals are the electrons. They have an electric charge of -1. The positively charge particles in the nucleus are protons. The overall charge is:

Overall charge = 3(-1) + 3(+1) = 0

The overall charge is zero. In other words, the lithium atom is neutral.

Answer:

Zero

Step-by-step explanation:

We are given that a lithium atom has positively charged protons and negatively charged electrons.

The sum of charges represents the charge of the lithium atom.

We have to find the charge on lithium atom.

We are  given that number of protons=3

Charge on one  proton=+1

Total charge on 3 protons=3(1)=+3

Number of electrons=3

Charge on  each electron=-1

Total charge on 3 electrons=3(-1)=-3

Sum of charges=3+(-3)=3-3=0

Hence, the charge of the atom =0

Therefore, lithium atom is neutral.
