Definition The stable isotope of phosphorus with relative atomic mass 30.973762 and nuclear spin 1/2.

What atom is P?

phosphorus (P), nonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.

What does P mean in atomic mass?

1. Phosphorus is a monoisotopic element and its atomic weight is determined solely by its isotope 31P.

What is P in the periodic table?

Phosphorus – Element information, properties and uses | Periodic Table.

Is P 37 A stable isotope?

Although phosphorus (15P) has 23 isotopes from 25P to 47P, only 31P is stable; as such, phosphorus is considered a monoisotopic element. The least stable is 25P with a half-life shorter than 30 nanoseconds. …

How many neutrons does P 31 have?

16 neutrons
This is the isotope phosphorus-31. It has 15 protons, 15 electrons, and 16 neutrons.

What is P atomic number?

Phosphorus/Atomic number

What is P in chemistry equation?

p (as an index) = number of product components, νi = stoichiometry number for component i in product mixture, ηj = stoichiometry number for component j in product mixture, σi = order of reaction for component i in reactant mixture.

How many chlorine isotopes are there?

Chlorine for example has two naturally occurring isotopes: Chlorine-35 and chlorine-37. Naturally occurring chlorine is 75 % Chlorine-35 and 25% chlorine-37. It has an average atomic weight of 35.5 amu.

How do you calculate isotopic abundance?

The equation can be set up as a percent or as a decimal. As a percent, the equation would be: (x) + (100-x) = 100, where the 100 designates the total percent in nature. If you set the equation as a decimal, this means the abundance would be equal to 1. The equation would then become: x + (1 – x) = 1.

What does the atomic weight tell you?

Atomic mass of an element tells us the number of times an atom of the element is heavier than of the mass of an atom of carbon-12. A unit suitable for the mass of atoms and the mass of subatomic particles is the atomic mass unit (u).

What is the atomic mass of P?

Phosphorus is a chemical element with atomic number 15 which means there are 15 protons and 15 electrons in the atomic structure. The chemical symbol for Phosphorus is P. Atomic mass of Phosphorus is 30.9738 u .

How is the atomic weight of an atom determined?

The weight of an atom is determined by the number of neutrons and protons that are present in the nucleus. The proton and neutron, which are similar in mass, each weighs approximately 1,836 times greater than a single electron, thus the mass contributed by electrons is insignificant when determining atomic weight or atomic mass.

What is the meaning of atomic weight?

Definition of atomic weight : the mass of one atom of an element specifically : the average mass of an atom of an element as it occurs in nature that is expressed in atomic mass units — see Chemical Elements Table
