Answer

Brief Explanations:

  1. Uses/Existences of Nitrogen - group members:
    • Nitrogen (N): Essential for life as a component of amino - acids and nucleic acids. Used in the production of ammonia for fertilizers.
    • Phosphorus (P): Vital for life, part of DNA, RNA, and ATP. Used in the production of fertilizers.
    • Arsenic (As): Historically used in pesticides, now has some applications in semiconductor manufacturing.
    • Antimony (Sb): Used in flame - retardants and some alloys.
    • Bismuth (Bi): Used in pharmaceuticals (e.g., Pepto - Bismol) and some low - melting alloys.
  2. Similarity to carbon group: Both the nitrogen group (Group 15) and the carbon group (Group 14) can form covalent bonds. Elements in both groups can exhibit multiple oxidation states.
  3. Properties of Pnictogens:
    • They have 5 valence electrons.
    • Tend to form covalent compounds.
    • Metallic character increases down the group.
  4. Interesting facts about Pnictogens (from periodic table website):
    • Nitrogen makes up about 78% of the Earth's atmosphere.
    • Arsenic compounds have been used in medicine historically.
    • Bismuth is the most naturally diamagnetic element.
  5. Properties/trends of oxygen - group members (Group 16):
    • Have 6 valence electrons.
    • Electronegativity decreases down the group.
    • Reactivity with metals generally decreases down the group.
  6. Importance of oxygen: It is essential for cellular respiration, the process by which cells generate energy. It is also necessary for combustion and is a major component of water.
  7. Allotrope: An allotrope is a different form of the same element in the same physical state. For example, oxygen has two common allotropes: dioxygen (O₂) and ozone (O₃), and carbon has allotropes like diamond, graphite, and fullerenes.
  8. Interesting facts about Chalcogens (from periodic table website):
    • Oxygen is the most abundant element in the Earth's crust.
    • Sulfur has many allotropes and is used in the production of sulfuric acid.
