Answer:

54

Step-by-step explanation:

Tellurium has an atomic number of 52, which means the neutral Te has 52 protons and 52 electrons. Te is -2 anion when it acquires 2 extra electrons so 52 + 2 = 54

Answer:

54

Step-by-step 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
