An element's atomic number is 52. How many electrons would an atom of this element have?

Answered this below already. Any neutral atom has exactly as many electrons as protons. This one is Tellurium

To determine the number of electrons in an atom, you need to know its atomic number.

The atomic number of an element represents the number of protons in the nucleus of its atom. In a neutral atom, the number of protons is equal to the number of electrons.

In this case, since the atomic number is given as 52, it means that the atom of this element has 52 protons in its nucleus. Therefore, it also has 52 electrons.

So, an atom of this element would have 52 electrons.
