Because as you add more electrons to the same valence shell, the effective nuclear charge increases and thus holds the valence shell closer.
sodium is a metal; silicon is a semimetal (metalloid); helium and sulfur are non metals
iron, nitrogen, sulfur, oxygen, silicon

No. Nuclear fusion will convert hydrogen to helium and, at higher temperatures, oxygen into silicon, phosphorus, and sulfur.
hydrogen (75%) and helium (25%), roughly yes, but to be more precise: The sun consists of 71 % Hydrogen, 27 % Helium, 1 % Oxygen and the last percent is made of Carbon, Nitrogen, Silicon, Magnesium, Neon, Iron and Sulfur.

Sulfur hexaiodide
Sulfur.
Quartz is the compound silicon dioxide (SiO2) and contains atoms of silicon and oxygen. It is usually clear. Sulfur is a simple element composed of sulfur atoms. It is opaque and yellow.
silicon silver and sulphur are all in diffront catigories
silicon is a better conductor of electric current than sulfur is.
Because Aluminum comes before Silicon in the dictionary
silicon
Yes, for example sulfur or silicon.
yes
chlorine is the smallest in size. The order of atomic size is chlorine < sulphur < phosphorus < silicon.
