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.
- Atomic number is the number of protons in an atom.
- Therefore, since the atomic number is 24, the number of protons likewise is 24;
Number of electrons is 24
