Answer:
The answer to your question is below.
Step-by-step explanation:
Atoms are composed by three different subparticles
- protons are small particles positive charged located in the nucleus.
- neutrons are small particles without a charged located in the nucleus.
- electrons are the smallest subparticles and are negatively charged.
In a neutral atom, the amount of positive charges (protons) is equal to the amount of negative charges (electrons) so it does not have any charge.
If a neutral atom gains one or more electrons it would be negative.
