Answer:

54

Explanation:

Given an atom of Tellurium;

         Tellurium has an atomic number of 52;

Unknown:

The number of electrons in a -2 anion

Solution:

   The atom is;

                            Te²⁻

A neutral tellurium atom has 52 electrons

When it forms an anion, it becomes negatively charged;

   This implies that the number of electrons becomes more,

  So, the number of electrons  = 52 + 2 = 54

So, the electrons are 54
