Question

how many protons are found in cr - 54? 64 30 24 0 none of the above

Explanation:

Step1: Recall the atomic number of Chromium

The atomic symbol \(Cr\) stands for Chromium. The atomic number of Chromium (\(Cr\)) is \(24\).

Step2: Relate atomic number to proton number

The atomic number of an element is equal to the number of protons in its nucleus. So, for \(Cr - 54\) (where \(54\) is the mass number \(A\), \(A=\text{number of protons}+\text{number of neutrons}\)), the number of protons is equal to the atomic number of \(Cr\).

Answer:

\(24\) (the third option in the given choices)
