Among these, neon and argon are most stable, as they are noble gases and have completely filled orbitals.
silicon
Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Sodium, Magnesium, Aluminum, Silicon, Phosphorus, Sulfur, Chlorine, Argon, Potassium, and Calcium.

When an elemnt has more than one form, where the atoms are bonded together differently these forms are called allotrpes. Carbon has a number of allotrpes, the best known are diamond and graphite. Other elements have allotropes such as phosphorus where ther are red phosphorus, white phosphorus black phosphorus and violet phosphorus.
chlorine is the smallest in size. The order of atomic size is chlorine < sulphur < phosphorus < silicon.
Among these, neon and argon are most stable, as they are noble gases and have completely filled orbitals.
Sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, and argon.
slicon of course
phosphorus-doped silicon ( n-type semiconductor) can be be produced by adding phosphorus to silicon to obtain a mixture, then heating and melting the obtained mixture. Or add phosphorus to already melted silicon.
phosphorus
Shells: 3 Orbitals: 9
Helium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Silicon, Phosphorus, Sulphur, Chlorine, and Argon are the main ones
Magnesium then silicon then chlorine
Chlorine
Sodium is in 3rd period and seven other elements are in same period they are Magnesium, Aluminium, Silicon, Phosphorus, Sulphur, Chlorine and Argon.
Aluminium, silicon, phosphorus, sulfur, chlorine and argon have the valence electrons (1 to 6 respectively) ending in 3p level
