Answer

Brief Explanations:

Answers based on periodic table properties, atomic structure, and subatomic particles.

Answer:

  1. a. Metal, b. Metalloid, c. Nonmetal, d. Metal, e. Nonmetal, f. Metal
  2. a. Alkaline earth metal, b. Halogen, c. Noble gas, d. Alkali metal, e. Alkaline earth metal, f. Noble gas
  3. Sodium (Na), Magnesium (Mg), Aluminum (Al)
  4. Carbon (C)
  5. Atoms are very small (~10⁻¹⁰ m). They have a tiny nucleus (~10⁻¹⁵ m, small relative to atom). Atoms are mostly empty space.
  6. Protons and neutrons in the nucleus; electrons in the electron cloud around the nucleus.
  7. Ion: Charged atom (gains/loses electrons). Isotope: Same element with different neutrons. Neutral atom: No charge (protons=electrons); ion has charge; isotope same protons, different neutrons.
