Question

What name is given to the triodes of atoms: ${}_7{}^{}\mathrm{N}^{13},{}_7{}^{}\mathrm{N}^{14}\mathrm{and}{}_7{}^{}\mathrm{N}^{15}$

Answer 1

• The name ‘isotope’ is given to the triodes of atoms${}_7{}^{}\mathrm{N}^{13},{}_7{}^{}\mathrm{N}^{14}\mathrm{and}{}_7{}^{}\mathrm{N}^{15}$.
• The isotopes of an element have the same atomic number but different atomic masses. The difference in their masses is due to the presence of the different numbers of neutrons.
• ${}_7{}^{}\mathrm{N}^{13},{}_7{}^{}\mathrm{N}^{14}\mathrm{and}{}_7{}^{}\mathrm{N}^{15}$ have six, seven, and eight neutrons respectively in their nucleus.
