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

VikaD [51]

Answer:

$^{31}_{15}P$ is the isotopic notation of the atom

Explanation:

The isotope notation is:

$^a_bX$

<em>Where a is the mass number = Number of protons + Number of neutrons</em>

<em>b is atomic number = Number of protons</em>

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.
