Answer 2

Answer:

Among the above options, Sodium is the element with the ‘most metallic character’ in the periodic table.

Explanation:

• In the periodic table, the ‘metallic character decreases’ across a period from left to right and increases as we move down the element group.
• This happens because the electrons lose due to an increase in atomic radius leading to lesser attraction between the ‘nucleus’ and the ‘valence electrons’.
• Metallic characters are represented by metals are grouped as alkali, alkaline earth, transition, basic, noble, ferrous, heavy, and precious metals.
