Question

Isotopic notation of phosphorus-29

Answer 1

Isotopic notation of phosphorus-29 is
`_(15) ^(29) P`

Step-by-step 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
  `_(Z) ^(A) X` 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
  `_(15) ^(29) P`
• Number of neutrons = 29-15 =14
• Number of protons=atomic number =15
