Identify Isotope Neutrons: Identify the number of neutrons in each isotope of hydrogen. Hydrogen has three isotopes: protium ( $1$ proton, $0$ neutrons), deuterium ( $1$ proton, $1$ neutron), and tritium ( $1$ proton, $2$ neutrons). The numbers given ( $1$ , $2$ , $3$ , $4$ ) do not correspond to the number of neutrons in the isotopes of hydrogen but rather to the isotope number for identification in this problem.
Calculate Total Neutrons: Calculate the total number of neutrons in the three isotopes. $\newline$ Protium has $0$ neutrons, deuterium has $1$ neutron, and tritium has $2$ neutrons. $\newline$ Total number of neutrons = $0$ (protium) + $1$ (deuterium) + $2$ (tritium) = $3$ neutrons.
