Answer:
¹⁴N has 7 neutrons and ¹⁵N has 8 neutrons
Explanation:
Nitrogen is a chemical element that belongs to the group 15 of the periodic table. It is a p-block element with an atomic number 7.
There are two stable isotopes of nitrogen: ¹⁴N and ¹⁵N
For ¹⁴N : mass number: A = 14, atomic number = number of protons : Z = 7
For ¹⁵N : mass number: A = 15, atomic number = number of protons : Z = 7
Since, mass number (A) = number of protons (Z) + number of neutrons (N)
⇒ N = A - Z
Therefore, the number of neutrons for ¹⁴N = 14 - 7 = 7
and the number of neutrons for ¹⁵N = 15 - 7 = 8
