Answer:
Sodium is a chemical element with the symbol Na (from Latin "natrium") and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table.
The second-lightest of the halogens, it comes as between fluorine and bromine in the periodic table and its characteristics are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature. So chlorine is an element which is defined as a nonmetal.

silvery-white, highly reactive metal. Sodium is an
alkali metal, being in group 1 of the periodic table.
2) Answer :
Chlorine is the second halogen, being a nonmetal in
group 17 of the periodic table. ... Corresponding to
periodic trends, it is intermediate in electronegativity
between fluorine and bromine (F: 3.98, Cl: 3.16, Br: 2.96, I:
2.66), and is less reactive than fluorine and more reactive
than bromine.
