If an atom has an atomic number of 15 and an atomic mass of 31, how many protons, neutrons and electrons does the atom contain?
The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of He 2s 2 2p 2, since its atomic number is 6. Atomic Number: 31. Atomic Weight: 69.723. Melting Point: 302.91 K (29.76°C or 85.57°F) Boiling Point: 2477 K (2204°C or 3999°F) Density: 5.91 grams per cubic. If gallium, atomic number 31, combines with selenium, atomic number 34, what is the most liekly formulabased on your knowledge of the periodic nature of the elements?

Atomic Number 312
1 Answer
This is the isotope phosphorus-31. It has 15 protons, 15 electrons, and 16 neutrons.
Explanation:
Recycle 2.1 crack. The atomic number for any element is the number of protons in its atomic nuclei. In a neutral atom, the number of electrons are the same as the number of protons. Sketchup 8 mac pro. The atomic mass (mass number) is the sum of the protons and neutrons in the nucleus. Mass number can vary due to the fact that the number of neutrons can vary. Isotopes are named for their mass numbers.
So, this element has 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number).
