Which of the following is the number of protons in a neutral atom of tin (Sn)?
A
50
B
48
C
118
D
74
Verified step by step guidance1
Identify the element in question, which is tin (Sn).
Recall that the number of protons in a neutral atom is equal to the atomic number of the element.
Look up the atomic number of tin (Sn) 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 atom of tin is equal to its atomic number, which is 50.
