Answer:

[tex]\frac{15}{7}N[/tex]

Explanation:

We already know that the mass number of an atom is the sum of the number of protons and the number of neutrons.

So, the mass number of this isotope is;

Number of protons = 7

Number of neutrons = 8

Mass number = 7 + 8 = 15

Hence, the isotope is;

[tex]\frac{15}{7}N[/tex]
