1. Atoms are composed of electrons, protons, and neutrons.
[K]
2. Electrons are positively charged whereas protons are
negative and neutrons are neutral. [K]
3. The atomic number indicates the number of protons plus
the number of neutrons. [K]
4. Isotopes are different varieties of the same element. They
differ in the number of neutrons they have. [K]
5. Electrons travel in paths called "orbitals" which occur at
distinct energy levels or shells outside of the nucleus. [K]
6. Valence electrons are the innermost electrons in an atom.
[K]
7. In a covalent bond, atoms share outermost electrons to
achieve stability. [K]
8. Neon is an example of a Halogen and it has achieved
stability and so it is unreactive. [T]
