Answer:
One positve charge
Explanation:
A neural atom is one that has equal number of protons and electrons. The protons are the positively charged subatomic particles in an atom. The electrons are the negatively charged particles in an atom.
For an atom to be charged during bond formation, it must lose or gain electrons. The number of electrons lost or gained conditions the charge on the ions it forms.
If in a neutral atom, it loses an electron, we see that the number of protons will now be more than the number of electrons by the 1 electron it lost. The charge will then be +1.
If a neutral atom gains an electron, the number of electrons will be more than that of the protons by 1. The charge will then be -1.
