Phosphorus
What is element 15? If it's the element on the periodic table with the atomic number 15, it would be Phosphorus which does have electrons, 15 of them. All elements on the periodic table have electrons.
An element with 15 electrons is phosphorus, which has an atomic number of 15. It has 15 protons and 15 electrons in its neutral state.
If phosphorus is neutral-charge, there are 15 of each.
The element with 7 electrons, 7 protons, and 8 neutrons is nitrogen-15 (15N).
Protons are particles with a positive charge, and in order for your atom to be neutral the positive charge must be cancelled out by adding negative charges of the same value. Electrons are negatively charged. So adding 15 electrons to 15 protons would result in a neutral atom. Also since your atom contains 15 protons it must be Phosphorus, element number 15.
15 electrons and 15 protons
The isotope with 15 protons, 16 neutrons, and 15 electrons is oxygen-31.
Elements are determined by their number of protons. Nitrogen has 7 protons but usually 7 neutrons as well. What you have here is a nitrogen isotope, an element with more or less neutrons than there are protons. Specifically, this is Nitrogen-15.
the number of protons equal the number of electrons. the element phosphorus has 15 electrons on its outer rings. the energy levels are 2,8,and 5. this element also has 15 protons and neutrons. written by: 8th grade student Kirby
Element X with 72 protons will have 72 electrons in a neutral state. The number of protons in an element is equal to the number of electrons in that element's neutral atom.
Indium has 49 protons and electrons.
The element with the most protons in Group 15 of the periodic table is bismuth with 83 protons. It is in the same group as nitrogen, phosphorus, arsenic, antimony, and moscovium, but has the highest number of protons in Group 15.
