1 label the various categories on the periodic table of elements. poor metals transition metals noble gases alkali metals semimetals

Answer

Brief Explanations:

The periodic table categorizes elements based on their properties. Alkali metals are in Group 1 (except hydrogen), alkaline - earth metals in Group 2, transition metals in the middle blocks, poor metals towards the right - bottom, semimetals along a diagonal staircase, noble gases in Group 18.

Answer:

  • Alkali metals: Li, Na, K, Rb, Cs, Fr (first column excluding H)
  • Alkaline - earth metals: Be, Mg, Ca, Sr, Ba, Ra (second column)
  • Transition metals: Sc - Zn, Y - Cd, Lu - Hg, Ac - Cn (middle blocks)
  • Poor metals: Al, Ga, In, Tl, Sn, Pb, Bi, Po, At (right - bottom metals)
  • Semimetals: B, Si, Ge, As, Sb, Te, Po (along the diagonal staircase)
  • Noble gases: He, Ne, Ar, Kr, Xe, Rn, Og (last column)
