Mass of neutron:
in mks unit = 1.674823 x 10^ -27 kg
in cgs unit = 1.674823 x 10^ -24 g
in mass unit = 1.00866544 u
in (mass neutron x c^2) = 939.5505 Mev

Can protons have twice the mass of neutrons?
No; the mass of proton is similar to the mass of neutrons.
How does the atomic mass help you find the neutrons?
Atomic mass = mass of protons + mass of neutrons.
Is this statement true neutrons have no charge and no mass?
Neutrons have no charge, but they do have mass.
What do neutrons add to an atom?
Neutrons add MASS to an atom.
Is the number of neutrons in an atom known as its mass number?
No, neutrons + protons = mass
What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
The mass of neutrons and electrons are about the same?
No. The mass of neutrons and protons are about the same. The mass of an electron is about 1/1800th the mass of a proton.
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
What is the sum of protons and neutrons in an atom?
Mass number!:)
The mass number of an element is equal to the total number of?
The mass number is the average atomic mass of all the isotopes that are found in nature.
Which subatomic particles makes up most of the mass off the atom?
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
