Answer

Brief Explanations:

  1. Metals are good conductors of heat and electricity. So the answer for "Good conductors of heat and electricity" is C. metals.
  2. Metals are found on the lower - left side of the Periodic Table. So the answer for "Found on the lower left side of the Periodic Table" is C. metals.
  3. Non - metals tend to form anions. So the answer for "Tend to form anions" is D. nonmetals.
  4. Non - metal solids are usually brittle. So the answer for "Solids are usually brittle" is D. nonmetals.
  5. Metals are malleable and lustrous. So the answer for "Malleable and lustrous" is C. metals.
  6. Atomic radius increases down a group and decreases across a period. O < Se < Cl < K.
  7. Atomic radius: P < Ti < Fe < Ba.
  8. First ionization energy increases across a period and decreases down a group. Rb < Sn < At < Xe.
  9. First ionization energy: Sr < Mg < C < F.
  10. Transition metals often form colored compounds and many can form ions with varying charges. So the answer is S. transition metals.
  11. Noble gases are relatively unreactive. So the answer is R. noble gases.
  12. Oxygen family elements tend to form ions with a - 2 charge. So the answer is P. oxygen family.
  13. Inner transition metals many are radioactive. So the answer is T. inner transition metals.
  14. Alkaline earth metals tend to form ions with a + 2 charge. So the answer is L. alkaline earth metals.
  15. Alkali metals are soft metals that react vigorously with water to form alkaline solutions. So the answer is K. alkali metals.
  16. Carbon family includes the technologically significant semimetal, silicon. So the answer is N. carbon family.
  17. Halogens are very reactive with high electronegativity. So the answer is Q. halogens.
