# What is the mass of a neutron charge and mass?

## What is the mass of a neutron charge and mass?

Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.

## How did the charge and mass of a neutron compared?

How do the charge and the mass of a neutron compare to the charge and mass of a proton? Their masses are nearly equal, but protons have a positive charge and neutrons have a neutral charge. If you lose an electron then you are left with more positive charge than negative charge.

What is the relative mass and charge of a neutron?

Subatomic particles

Subatomic particle Relative mass Relative charge
Proton 1 +1
Neutron 1 0
Electron 0.0005 -1

What is the charge of a neutron?

no charge
Proton—positive; electron—negative; neutron—no charge. The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another in a neutral atom.

### How is the mass number computed?

Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

### What particle has the largest mass?

The subatomic particle with the largest mass is the neutron. However, the difference in mass between a neutron and proton is very small.

What is the atomic mass number equal to?

protons
An element’s mass number (A) is the sum of the number of protons and the number of neutrons.

What does atomic mass equal to?

The atomic mass of an atom is an empirically measured property, which is equivalent to the sum mass of protons, neutrons, and electrons that make up the atom (with a small adjustment for nuclear binding energy).

#### How does the mass of a neutron compare to a proton?

The mass of a neutron is slightly greater than the mass of a proton. The neutron has no electric charge while the proton has a positive charge (+1 elementary charge). The mass of a neutron and a proton are 1.67492729(28)×10−27 kilograms and 1.672621637(83)×10−27 kilograms respectively.

#### How is the charge of a neutron determined?

The neutron has no measurable electric charge. It is unaffected by electric fields. It has a magnetic moment; however, it is affected by magnetic fields. The magnetic moment of a neutron has a negative value because its orientation is opposite to the spin of the neutron. A free neutron remains unstable, with a proton, electron,

How is the electron configuration of a nucleus determined?

The electron configuration is determined by the charge of the nucleus, which is determined by the number of protons, or atomic number. The number of neutrons is the neutron number. Neutrons do not affect the electron configuration, but the sum of atomic and neutron numbers is the mass of the nucleus.

What do you call a nuclide with the same neutron number?

Nuclides with the same neutron number, but different atomic number, are called isotones. The atomic mass number, A, is equal to the sum of atomic and neutron numbers. Nuclides with the same atomic mass number, but different atomic and neutron numbers, are called isobars .
