Solution

  1. Elements with a valency of 1 include hydrogen, sodium, potassium, etc.

  2. Examples of atoms:

    • Monoatomic: Helium (He), Neon (Ne), Argon (Ar)
    • Diatomic: Hydrogen (H2), Nitrogen (N2), Oxygen (O2)
    • Polyatomic: Ozone (O3), Sulfur (S8), Phosphorus (P4)

  3. Difference between Ferrous and Ferric:

    • Ferrous refers to iron with a +2 oxidation state (Fe2+).
    • Ferric refers to iron with a +3 oxidation state (Fe3+).

  4. Difference between Nitric, Nitride, Nitrate:

    • Nitric refers to nitric acid (HNO3).
    • Nitride refers to a compound containing nitrogen with a -3 oxidation state.
    • Nitrate refers to a compound containing the nitrate ion (NO3-).

  5. Difference between Isotopes and Isobars:

    • Isotopes are atoms of the same element with different numbers of neutrons, hence different atomic masses.
    • Isobars are atoms (nuclei) of different elements with the same number of nucleons, hence the same atomic mass number.

  6. The mass of a chlorine atom in the atmosphere cannot be calculated without additional information. However, the atomic mass of chlorine is approximately 35.5 atomic mass units.

  7. The first person to propose that the atom as a whole is electrically neutral was J.J. Thomson.

  8. Applications of radioactive isotopes:

    • In medicine, for example, radioactive iodine (I-131) is used to treat thyroid cancer.
    • In archaeology, carbon-14 is used for radiocarbon dating.
    • In industry, cobalt-60 is used for sterilization of medical supplies and food irradiation.
