## How many protons and neutrons does phosphorus-31 have?

Diagram of the nuclear composition and electron configuration of an atom of phosphorus-31 (atomic number: 15), the most common isotope of this element. The nucleus consists of 15 protons (red) and 16 neutrons (blue). 15 electrons (green) bind to the nucleus, successively occupying available electron shells (rings).

## What does the number mean in phosphorus-31?

Once you know the mass number, you can use the element’s atomic number to find the number of neutrons it contains in its nucleus. This means that the most common isotope of phosphorus is phosphorus-31, meaning that its mass number is equal to 31 .

How many valence electrons does phosphorus-31 have?

The outermost orbitals, 3s2 3p3 , contains 5 electrons. Thus, valence electrons for P is 5.

How many neutrons are in an isotope of phosphorus with a mass number of 31?

16
For Phosphorus, 30.97 becomes 31, which represents the mass number for the most common isotope of Phosphorous. To find neutrons we use A = N + Z. Here 31 = 15 + x. Solving for x we get 16, which is the number of neutrons for the Phosphorous isotope with a mass number of 31 (called Phosphorous-31 or P-31).

### How many neutrons are in phosphorus 32?

17 neutrons
Phosphorus 32 (P-32) is the phosphorus isotope whose nucleus consists of 15 protons and 17 neutrons. It disintegrates by emitting a β- (1.71 MeV) particle in 32S with a half-life of 14.263 days. It is an artificial radioactive substance obtained by neutron bombardment of stable phosphorus.

### How many protons neutrons and electrons are in phosphorus 32?

Phosphorus-32 is composed of 15 protons, 17 neutrons, and 15 electrons.

How many neutrons are in phosphorus 30?

Phosphorus has 16 neutrons.

How many neutrons are in phosphorus 33?

Terms in this set (14) What is its mass number? 17 protons, 17 electrons, and 18 neutrons.

## What is the use of phosphorus-31?

Phosphorus-31 NMR spectroscopy is an analytical chemistry technique that uses nuclear magnetic resonance (NMR) to study chemical compounds that contain phosphorus. Phosphorus is commonly found in organic compounds and coordination complexes (as phosphines), making it useful to measure 31P NMR spectra routinely.

## Is Phosphorus-31 an isotope?

Phosphorus-31 atom is the stable isotope of phosphorus with relative atomic mass 30.973762 and nuclear spin (1)/2. A non-metal element that has the atomic symbol P, atomic number 15, and atomic weight 31. It is an essential element that takes part in a broad variety of biochemical reactions.

How many neutrons are in phosphorus-32?

How many electrons and neutrons does phosphorus 31 have?

So, this element has 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number). This isotope is phosphorus-31, which has atomic number 15. Click to see full answer. Likewise, how many electrons and neutrons does phosphorus have?

### What is the atomic number of the element phosphorus?

Phosphorus is a chemical element with atomic number 15 which means there are 15 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.

### What is the total number of neutrons in an atom?

The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z.

Which is the most stable isotope of phosphorus?

Mass numbers of typical isotopes of Phosphorus are 31. 23 isotopes of phosphorus are known, ranging from 25P to 47P. Only 31P is stable and is therefore present at 100% abundance.
