The element that has 15 protons in it's protons is phosphorus (P).
Phosphorous - the only stable isotope is 31P.
Phosphorus - 32
Phosphorus (P)
the answer is phosphous
Phosphorus contains 15 protons
Phosphorous atom
nitrogen
Phosphorus

16 ... if it's not ionized. A neutral atom would have 16 electrons, one negative charged electron for each positive charged proton. Now an atom does not have to be neutral, it can have more or less electrons, which is called an ion. 16 Protons would make this a Sulfur atom, which is going to try to aquire 2 more electrons to have a complete orbital shell.
Wood contains Cellulose (40-50%), hemixenluloza(15-25%) and lignin(15-30%) mainly.
atoms consist of protons, neutrons and electrons. The protons and neutrons are clumped together in the centre. This is called the nucleus. The electrons "orbit" the nucleus. We say there are different "electron shells", the first layer has 2 electrons, second has 8 and depending on how many electrons an atom has determines what element it is.
This is no exactly fixed point. We say, is must be higher than the upper hearing limit. And that is around 20 kHz.
There are a handful of elements that undergo positron decay. Positron decay, called positron emission or beta decay (beta plus decay) happens in carbon-11, nitrogen-13, oxygen-15, fluorine-18, potassium-40 and iodine-121. Let's look at what's happening. In the nucleus of these isotopes, the weak force mediates the conversion of a proton into a neutron, a positron and a neutrino, and also a photon or gamma ray. In the case of carbon-11, its decay scheme will look like this: 11C → 11B + e+ + νe + 0.45 MeV The carbon-11 atom is converted into a boron-11 atom, a positron (e+), a nuetrino (ve) and the 0.45 MeV gamma ray. (The MeV is a million electron-volts.) The new element, that new atom of boron, recoils a bit from the event, and the positron and the neutrino come out at high speed (at a high kinetic energy). The gamma ray will be moving at the speed of light (for the medium through which it is passing). You'll note that since a proton in the nucleus was converted into a neutron, the atomic number changes. It goes down one. A new element forms, as was seen in this illustration. Oh, and let's not forget that since the number of protons in the nucleus went down by one, one of the electrons in the electron cloud will no longer be "held" there. It will be released and will wander off. Links can be found below for more information.
Any atom should have equal number of protons and electrons. If the atom contains 15 protons then it must contain 15 electrons.
Nitrogen (II) oxide, or NO contains one nitrogen atom (Z=7) and one oxygen atom (Z=8), for a total of 15 protons.
All phosphorus atoms have 15 protons (hence their atomic number of fifteen). Assuming the atom is neutral, it will also have an equal amount of electrons.
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
P is a p block non metal. Atom contains 15 protons.
Phosphorus contains 15 protons.Its atomic number is also 15.
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.
An atom with 15 protons is an atom of phosphorus (P).
The mass number of an atom is the number of protons plus the number of neutrons in its nucleus. So an atom with 15 protons and 10 neutrons would have a mass number of 15 + 10 = 25.
Nitrogen 15 contains: 7 protons 8 neutrons 7 electrons "15" is added to the name because it is an isotope and contains inequal amounts of protons and neutrons (in this case, an extra neutron).
