What else can I help you with?
What two particles in an atom have approximatley the same mass?
Proton and neutron.
What two particles of the atom are added together to get the atomic mass?
4
What are the two subatomic particles with a mass?
In the atom, protons and neutrons; the mass of the electron is very small.
What are the two parts of the atom that have a mass of 1 atomic mass unit?
The two parts of the atom that have a mass of approximately 1 atomic mass unit (amu) are protons and neutrons. Protons are positively charged particles found in the nucleus of an atom, while neutrons are neutral particles that also reside in the nucleus. Together, these particles make up the majority of an atom's mass. Electrons, on the other hand, have a negligible mass compared to protons and neutrons.
What particle or particles carry virtually all the mass (weight) of any atom?
Virtually all of the mass of an atom is carried by the proton and the neutron. The electron has very, very little mass relative to these two particles.
Which two particles in the atom have the same mass?
No two subatomic particles have the exact same mass. The proton and the neutron, however, come close. Neutrons are heavier than protons by only 2.3 X 10-30 kg.
What two atomic particles are in the nucleus of an atom?
Protons and neutrons are the two particles that are in the nucleus of an atom. Electrons orbit around the atom
What two subatomic particles do you add together to get the mass number?
The two subatomic particles you add together to get the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but together they contribute to the mass of an atom.
What two subatomic particles are added together to determine the mass number?
The two subatomic particles added together to determine the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but both contribute to the mass of an atom.
Which two particles make up most of the mass of a C-12 atom?
proton and neutron
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
What two particles each account for half of the mass of the atom?
Protons, Neutrons, Electrons, Alpha Particles, any of those.... just guessing (:
