Answer :
Final answer:
Sodium is classified as a metal, specifically an alkali metal, on the periodic table. It has high reactivity and exhibits typical metallic properties such as conductivity and malleability. Being in group 1, it shares characteristics with other metals.
Explanation:
Classification of Sodium
Sodium, represented by the symbol Na on the periodic table, is classified as a metal. It belongs to the group of alkali metals, which are known for their shiny appearance and high reactivity. Sodium is found in group 1 and has one electron in its outermost shell, making it very eager to lose that electron and form positive ions.
Being a representative element, sodium exhibits typical metallic properties, including good conductivity of electricity and heat, and malleability, which allows it to be shaped and deformed without breaking. Other examples of metals in the periodic table include potassium (K) and calcium (Ca), while nonmetals like oxygen (O) and carbon (C) are found in groups to the right.
