Answer to Problem 9STP
The number of protons is
Explanation of Solution
The protons and neutrons of an atom are present in the nucleus of an atom whereas the electrons are always moving around the nucleus of an atom that is they possess kinetic energy. Thus, the number of protons and neutrons is to be calculated for an atom of
The given symbol of an atom is
Since,
So,
The number of protons in the nucleus of an atom of
Using, Mass number = Number of neutrons + number of protons, the number of neutrons present in the nucleus of an atom of
Hence, the correct option is (d) as the number of protons is
