The mass of 12 protons is approximately equal to 12 atomic mass units.
what is the mass number of an atom with 12 protons and 12 neutrons
one neutron
a neutron
The proton and the neutron each have a mass approximately equal to one atomic mass unit.
It is true that neutrons have no charge, but they do have mass. This mass is approximately 1.0087 AU, or 1.67*10^-27 kilograms.
You think probable to proton and neutron.
The charge of a proton is positive 1 and the mass is approximately 1 atomic mass unit
No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons. Therefore, an alpha particle has approximately 4 times the mass of a proton or neutron.No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons. Therefore, an alpha particle has approximately 4 times the mass of a proton or neutron.No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons.

1/1836 the mass of a proton
Approximately 1836
The mass of a proton is equal to a neutron.
The proton and the neutron each have a mass approximately equal to one atomic mass unit.
It is true that neutrons have no charge, but they do have mass. This mass is approximately 1.0087 AU, or 1.67*10^-27 kilograms.
A neutron has about the same mass as a proton.
the neutral or no charge particle of an atom:it is located in the nucleus;has the same mass as the proton.
You think probable to proton and neutron.
Neutron
The charge of a proton is positive 1 and the mass is approximately 1 atomic mass unit
The proton mass is about 2,000 times greater than the electron mass.
