# How many protons electrons and neutrons are in P?

## How many protons electrons and neutrons are in P?

For example, the element phosphorus (P) has an atomic number of 15 and a mass number of 31. Therefore, an atom of phosphorus has 15 protons, 15 electrons, and 16 neutrons (31-15 = 16).

### How many electrons would P have *?

2, 8, 5
Phosphorus/Electrons per shell

#### What is p2 on the periodic table?

How many protons neutrons and electrons does P 31 have?

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

What has 15 protons and 16 neutrons?

phosphorus
A nucleus of stable phosphorus has 15 protons and 16 neutrons.

## What does S stand for on the periodic table?

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

### How many electrons does 31 P have?

How many electrons does phosphorus 31 have? Isotopes are named after their mass number. This element has 15 protons (atomic number), 15 electrons and 16 neutrons (mass number minus atomic number). This isotope is phosphorus31 with atomic number 15.

#### How many neutrons does P 3 have?

16

Symbol P3- Br-
Neutrons 16 45

How many neutrons are in an element?

The atomic number of the element equals the number of protons. Calculating the number of neutrons then becomes atomic mass of the isotope minus the atomic number of the element equals the number of neutrons. For uranium-235, atomic number 92, the number of neutrons is 235-92=143, or 143 neutrons.

What is the electron configuration of P?

In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Phosphorous go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons.

## How do you determine the number of neutrons in an atom?

To find the number of neutrons in an atom of the isotope, simply subtract the number of protons (atomic number). So, carbon-13 has 7 neutrons, because carbon has atomic number 6.
