1. A positively charged particle in an atom is a: proton.
2. A particle with no charge is a: neutron.
3. These two particles form a dense center called the: nucleus.
4. Each particle that moves around this center is called an: electron.
An atom refers to the smallest, indivisible unit made up of matter and forms all chemical elements.
In Chemistry, an atom is made up of three (3) distinct subatomic particles and these include:
1. Protons: these are the positively charged subatomic particles found in an atom and they have a magnitude of +1.
2. Neutrons: these are the neutral subatomic particles found in an atom and they have a magnitude of 0.
3. Electrons: these are the negatively charged subatomic particles found outside the nucleus of a chemical element with a magnitude of -1.
In conclusion, the nucleus is a dense center formed by the proton and neutrons.
