Which of the following is the atomic number of rubidium?
A
47
B
37
C
53
D
85
Verified step by step guidance1
Understand that the atomic number of an element is the number of protons in the nucleus of an atom of that element.
Recall that rubidium is an element found in the periodic table, and each element has a unique atomic number.
Look up rubidium in the periodic table to find its atomic number, which is usually listed above the element symbol.
Identify that the atomic number corresponds to the number of protons and determines the element's identity.
Confirm that the atomic number of rubidium is 37, which matches one of the given options.
