Sodium Telluride Formula

The molar mass of sodium telluride is calculated by adding the atomic masses of one sodium atom (22.99 g/mol) and one tellurium atom (127.60 g/mol), then multiplying the sum by two since there are two atoms of sodium and one atom of tellurium in each formula unit of sodium telluride. Therefore, the molar mass of sodium telluride is:

(2 x 22.99 g/mol Na) + (1 x 127.60 g/mol Te) = 178.58 g/mol

Sodium telluride (Na2Te) is an ionic compound that consists of sodium cations (Na+) and telluride anions (Te2-). The structure of Na2Te can be described as a crystal lattice where each sodium ion is surrounded by six telluride ions and each telluride ion is surrounded by six sodium ions.
