What part of the atom contains most of its mass?
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
The region in an atom that contains most of the mass is called?
Most of the atom's mass is concentrated in the nucleus.
The mass of an atom compared to the mass of a carbon-12 atom is called the?
Isotope.
Protons are so much more massive than electrons that you can neglect the mass of electrons when determining the mass of an atom?
Atomic mass is based on the proton and neutron. For the most part the mass of an electron is infinitesimally small.

The nucleus, made up of protons and neutrons, contains most of an atom's mass.
What is most likely true of an atom with a mass of 15 amu?
An atom with a mass of 15 amu is most likely a nitrogen atom, as the atomic mass of nitrogen is approximately 14.01 amu. This means that the atom may have gained or lost a particle, altering its mass slightly.
Where is the great majority of the mass of the atom found?
The great majority of the mass of an atom is found in the nucleus, where protons and neutrons are located. The nucleus is incredibly dense and accounts for almost all of the atom's mass, while electrons, which are much smaller and lighter, contribute very little to the overall mass of the atom.
