Isotopic notation of phosphorus-29 is
Explanation:
- Isotopes are atoms with equal number of protons but different number of neutrons at its nucleus.
- The isotopic notation for any element can be written as where X represents the chemical symbol ,A represents mass number and Z represents atomic number
- The atomic number for phosphorus is 15
- Isotope's mass number for phosphorus-29 is 29
- The chemical symbol for phosphorus is P
- Hence Isotopic notation is
- Number of neutrons = 29-15 =14
- Number of protons=atomic number =15
