Select the correct statement(s) about the temporary IUPAC systematic names (used before a permanent name is approved) of elements with Z greater than 100.

  1. AThe element with Z = 112 is named ununbium.
  2. BThe element with Z = 104 is named unnilquadium.
  3. CThe element with Z = 118 is named ununoctium.
  4. DThe element with Z = 113 is named ununtrium and has Z = 114.

Answer: A, B, C

The roots are nil 0, un 1, bi 2, tri 3, quad 4, pent 5, hex 6, sept 7, oct 8, enn 9. So 112 is ununbium, 104 is unnilquadium and 118 is ununoctium, so A, B and C are true. D is false: ununtrium is Z = 113 only, not 114.
