How many protons are present in an atom of tin (Sn)?
A
50
B
74
C
118
D
48
Verified step by step guidance1
Identify the element in question, which is tin (Sn).
Recall that the number of protons in an atom is equal to the atomic number of the element.
Look up the atomic number of tin (Sn) on the periodic table.
Note that the atomic number of tin (Sn) is 50, which means it has 50 protons.
Conclude that the number of protons in an atom of tin is 50.
