Respuesta :

Answer:b

Explanation:

don’t listen to the guy in the comments

The element contains 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number).

What are protons, neutrons and electrons?

The atomic number for any component exists as the number of protons in its atomic nuclei. In a neutral atom, the number of electrons exists exactly as the number of protons. The atomic mass (mass number) exists as the totality of the protons and neutrons in the nucleus. The mass number can change due to the particular that the number of neutrons can vary. Isotopes exists called for their mass numbers.

So, this element contains 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number).

This isotope exists phosphorus - 31, which contains atomic number 15.

Therefore, the correct answer is option B. 15 protons, 16 neutrons, and 15 electrons.
