An atom of the element chromium has an atomic number of 24 and a mass number of 52. How many electrons are in an uncharged atom of chromium? 0
24
28
52

24

Explanation:

In an uncharged atom, the number of protons is always equal to the number of electrons. For example, carbon atoms include six protons and six electrons, so carbon's atomic number is 6.

Similarly, since an atom of chromium contains 24 protons, it also contains the same amount of electrons, which is 24.

24 is your answer
