Question

An isotope has 15 protons, 16 neutrons, and 15 electrons. What is the isotopic notation of the isotope

Answer 1

`^(31)_(15)P` is the isotopic notation of the atom

Step-by-step explanation:

The isotope notation is:

`^a_bX`

Where a is the mass number = Number of protons + Number of neutrons

b is atomic number = Number of protons

The atomic number define the nature of the atom, the element with atomic number = 15 is phosphorus, P:

`^a_bP`

a = 15 protons + 16 neutrons = 31

b = 15

`^(31)_(15)P` is the isotopic notation of the atom.
