Answer:

24

Explanation:

Given parameters:

Atomic number = 24

Mass number  = 52

Unknown:

Number of electrons in the uncharged atom of chromium = ?

Solution:

In an uncharged atom of chromium, the number of protons and electrons are the same.

Once we can find the number protons, we can simply equate it to the number of electrons.

  • Therefore, since the atomic number is 24, the number of protons likewise is 24;

Number of electrons is 24
