How many protons are present in an atom with an atomic number of 23 and a mass number of 51?
A
28
B
74
C
23
D
51
Verified step by step guidance1
Understand that the atomic number of an element represents the number of protons in its nucleus.
Identify the given atomic number, which is 23 in this problem.
Recall that the mass number is the sum of protons and neutrons, but it does not affect the number of protons directly.
Since the atomic number equals the number of protons, the number of protons in this atom is simply 23.
Therefore, the answer to how many protons are present is the atomic number itself, which is 23.
