Q. Determine the Number of neutrons?
Isotopes of an element can as well be specified by writing the mass number of the isotope following a hyphen after the name of the element. For instance hydrogen's isotopes are able to be written as hydrogen-1 and hydrogen-2 or H-1 and H-2 respectively.
Evoke that the number of protons in an atom's nucleus is its atomic number. Alternative atomic number for the number of protons gives the following relationship.
Number of neutrons = mass number + atomic number
You are able to use this relationship to determine any one of the variables if you know the other two.
