Which of the following is the number of protons in a platinum (Pt) atom?
A
74
B
82
C
80
D

Verified step by step guidance1
Recall that the number of protons in an atom is given by its atomic number, which is unique for each element.
Identify the element in question, which is platinum (Pt).
Look up the atomic number of platinum on the periodic table; this number represents the number of protons in a platinum atom.
Verify that the atomic number corresponds to one of the given options.
Conclude that the number of protons in a platinum atom is equal to its atomic number.
