By Ritesh|Updated : October 27th, 2022

1 valence electrons are present in Sodium. The periodic table's Group 1 classifies sodium as an alkali metal. Sodium (Na) has an atomic number of 11 and an electronic configuration of 2, 8, and 1. 2 valence electrons are found in Group 2 elements. 4 valence electrons are found in Group 14 elements. 8 valence electrons are found in Group 18 elements (Noble gases).

Physical Properties of Sodium

  • The metal lustre on sodium is very intense. It closely resembles silver in terms of colour.
  • When the temperature is normal, it is so malleable that fingers may press it into the shape of leaves.
  • Sodium compounds tarnish more slowly than potassium compounds when exposed to air.
  • In the air, sodium reacts with oxygen to generate sodium oxide, which then combines with water vapour to form a sodium hydroxide film.

Uses of Sodium

  • Additionally, it is utilised in soaps, the purification of molten metals, sodium vapour lamps, and enhancing the structure of some alloys.
  • Sodium is a component of sodium chloride, a key substance present in the environment that supports life.
  • Making esters and producing organic molecules both depend on sodium.
  • Glassmaking requires solid sodium carbonate.

Summary:

How many valence electrons are present in Sodium? (a) 1 (b) 2 (c) 4 (d) 8

Sodium has a valence electron configuration of 1. It is classified as a group 1 element in the periodic table.
