Question

anatomy of an atom the basic model
what is located at the center of an atom?
what are the parts of an atom called?
what subatomic particles are located in the nucleus?
what subatomic particles dont have a charge?
which subatomic particles are the lightest?
what are electrons?
what is the periodic table of elements?
what is an isotope?
what is the atomic number equal to?
what is the atomic mass number equal to?

Explanation:

1. Protons and neutrons are located in the nucleus.
2. Neutrons don't have a charge.
3. Electrons are the lightest subatomic particles.
4. Electrons are negatively - charged subatomic particles that orbit the nucleus.
5. The Periodic Table of Elements is a tabular display of the chemical elements, organized by atomic number, electron configuration, and recurring chemical properties.
6. An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons.
7. The atomic number is equal to the number of protons in an atom.
8. The atomic mass number is equal to the sum of the number of protons and neutrons in an atom.
