chlorine is the smallest in size. The order of atomic size is chlorine < sulphur < phosphorus < silicon.
Sodium is in 3rd period and seven other elements are in same period they are Magnesium, Aluminium, Silicon, Phosphorus, Sulphur, Chlorine and Argon.
francium has the largest ionic radius
Chlorine fist as it is in group 7. Then group 6 to 1 in that order. i.e. Sulphur, Phosphorus, Silicon, Aluminium, Magnesium, then sodium.

Si is the symbol for silicon. Cl refers to chlorine. The compound formed by these elements is silicon chloride SiCl4.
Sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, and argon.
Helium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Silicon, Phosphorus, Sulphur, Chlorine, and Argon are the main ones
Sodium is in 3rd period and seven other elements are in same period they are Magnesium, Aluminium, Silicon, Phosphorus, Sulphur, Chlorine and Argon.

slicon of course
Si is the symbol for silicon. Cl refers to chlorine. The compound formed by these elements is silicon chloride SiCl4.
Phosphorus is in the 15th column of the periodic table (Nitrogen group) That means that it has similar valence shell electronic properties as nitrogen arsenic antimony bismuth
Hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium, and calcium.
Among these, neon and argon are most stable, as they are noble gases and have completely filled orbitals.
