Question
Composition of the nuclei of two atomic species X and Y are given as under
\quad\quad\quad\quad\quad\quad\quadX\quadY
Protons \quad=\,\, 6 \quad 6
Neutrons \,=\,\, 6 \quad 8
Give the mass numbers of X and Y. What is the relation between the two species?
Answer
Mass Numbers:
Mass Number of X = Protons + Neutrons =
6 + 6 =12Mass Number of Y = Protons + Neutrons =
6 + 8 =14
Relation:
Since both species X and Y have the same number of protons (atomic number = 6) but different mass numbers (12 and 14), they are Isotopes. (They are isotopes of Carbon).
