Question

1. atomic number is based on the number of these subatomic particles in an atom of a particular element.
2. atoms share these subatomic particles when they combine to form molecules.
3. the atomic mass does not include these subatomic particles in the calculation.
4. ionic bonds are formed when these subatomic particles are completely transferred from one atom to another atom.
5. isotopes have the same numbers of protons and
6. these subatomic particles carry a negative charge and are found in orbitals that surround the nucleus.
7. ions have lost or gained these subatomic particles.
8. along with protons, these subatomic particles are situated in the nucleus of an atom.

Explanation:

1. The atomic number is determined by the number of protons in an atom of an element.
2. Atoms share electrons when forming molecules.
3. Atomic mass calculation does not include electrons as they have negligible mass.
4. Ionic bonds form when electrons are transferred between atoms.
5. Isotopes have the same number of protons and electrons (in a neutral state).
6. Electrons are negatively - charged and found in orbitals around the nucleus.
7. Ions are formed by losing or gaining electrons.
8. Neutrons, along with protons, are located in the nucleus of an atom.
