Sulfur (S), because it is a non-metal that is brittle, and a bad conductor that electricity. Back Neon is a nonmetal, that is part of the noble gases, as such it is no a solid.

Silicon (Si), because non-metallic nature are most noticeable in the elements in the top right corner of the periodic Table, to the best of the "black staircase."
Which symbol to represent a particle that has the same total number of electrons as S^2-?-O^2--Si-Se^2--Ar
Argon (Ar). Sulfur (S) gains 2 electrons to kind the S^2- ion for a full of 18 electrons. The argon (Ar) atom also has 18 electrons.
According come the periodic Table, which facet has more than one hopeful oxidation state? -cadmium-iron-silver-zinc
Al2(SO4)3. This is since The ion of transitional steels (groups 3-11) space usually colored both in hard compounds and also in solution. In this case, aluminum is not a transitional metal, therefore the compound is colorless.
Sodium(Na). This is because metals prefer sodium lose electrons when they kind ions so their ionic radius is smaller sized than your atomic radius.
