Question

Sodium [Na] and Sulphur [S] both are present in the third period of the modern periodic table. Which is more metallic and why?

Answer 1

Hint-The periodic table is the ordered set of all chemical elements, i.e. the total sum of protons in the atomic nucleus. There is a recurrent pattern which is known as "periodic law" in the properties of the chemical elements that have identical properties in the same column (group).

Complete step by step answer:
> Sodium (Na), alkaline metal group chemical compound of the periodic table. Sodium is a silver-white metal that's extremely soft. Sodium is the most common alkali metal, with 2.8% of the world crust being the sixth most prevalent substance on earth. Compounds, especially common salt — sodium chloride — are abundantly present in nature.
> The nonmetallic chemical element of the group oxygen, which is also written Sulphur (sulfur), is one of the most reactive elements. Pure sulfur is a completely tasteless, odorless, solid (brittle), pale-yellow solid, weak electricity conductor, insoluble in water.
> Atoms are classified as metals if they have the potential to lose electrons. Since the third phase of the existing periodic table is present, both Sodium[Na] and Sulphur [S] but sodium belongs to the alkaline earth metal, which is extremely reactive. We also know that as we pass over the period the metallic character is diminishing. As sodium is in group 1, Sulphur is in group 16, sodium is always considered as more metallic than Sulphur.

Note-A metal is an element that retains the electrons in the outer shell weakly. In short, the more the electronegativity of an element, the greater the ability of that element to hold on to electrons and the less metallic it becomes.
