Verified step by step guidance1
Recall that the number of protons in a neutral atom is equal to its atomic number.
Identify the element given, which is chromium (Cr).
Look up the atomic number of chromium on the periodic table; this number represents the number of protons.
Understand that the atomic number is unique to each element and defines the element's identity.
Conclude that the number of protons in a neutral chromium atom is equal to its atomic number, which is 24.
