The net charge of an atom is determined by the difference between the number of protons and electrons. Protons are positively charged, while electrons are negatively charged.
In this case:
- Number of protons = 12
- Number of electrons = 13
To find the net charge: Net Charge = Number of Protons - Number of Electrons Net Charge = 12 - 13 = -1
Therefore, the net charge of the atom is -1.
