An atom of phosphorus has 15 electrons in total. This can be determined based on its atomic number, which is 15.
The sulfide ion, S2-.
phosphorus have 15 electron because you know the atomic number to know electron
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
The atomic number of phosphorus is 15.its electronic configuration is 2,8,5.outermost shell has 5 electrons. it can accommodate 3 more electrons to complete its octet.so its valency is 3. and it has 5 electrons on its valence shell.
The atomic number of phosphorus is 15. So there are 15 protons and 15 electrons in phosphorus.
An atom of phosphorus has 15 electrons in total. This can be determined based on its atomic number, which is 15.
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.
A neutral atom with an atomic number of 15 (phosphorus) will have 5 electrons in its outermost energy level. This is because the atomic number tells us the number of protons, which is equal to the number of electrons in a neutral atom. The outermost energy level for phosphorus is the third energy level.
The most stable isotope of phosphorus is phosphorus-31. The atomic number of phosphorus is 15, so it has 15 protons. In a neutral atom, there will also be 15 electrons. The number of neutrons is mass number minus atomic number, which is 31-15, so the number of neutrons is 16.
There are a variety of isotopes that have 30 neutrons. It isn't the number of neutrons that determines an element, but the number of protons. Electrons generally balance the number of protons.
The number of protons and electrons are equal to the atomic number. For P, this is 15. The number of neutrons is the atomic mass minus the atomic number (31 - 15 = 16). So Phosporous has 15 electrons and protons, and 16 neutrons.
