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 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.
Do the electrons of an atom contribute to mass of an atom?
Protons have a positive charge and weigh 1 AMU Neutrons have a neutral charge and weigh 1 AMU Electrons have a negative charge and 1184 electrons weigh 1AMU so they are thought to add nothing to the mass of an atom. You may want to check out Bohr's model or the duet/octet rule.
What is the mass of an aluminum atom?
An Aluminum atom is 26.9815 AMU on *average*.
What part of the atom contains the least atomic mass?
Electron. Contains basicaly no mass what so ever.
Which in an atom has the least mass in an atom?

What part of the atom contains the majority of mass an atom has?
The nucleus contains the mass.
What is the part of the atom that makes up the mass of the atom?
the nucleus of the atom
What particle in the atom is the least massive?
Electrons are the least massive particles in an atom. They have a mass that is about 1/1836th the mass of a proton or neutron.
What part of an atom makes up the mass of an atom?
the nucleus
Part of an atom that has least mass?
Electrons have the least mass of the three main subatomic particles found in an atom (protons, neutrons, and electrons). They have a mass that is approximately 1/1836 times that of a proton or neutron.
What is the smallest part of the atom that has almost no mass?
The electron is the smallest subatomic particle in an atom and has almost no mass compared to the proton and neutron.
What particle found in an atom has the least mass?
the electron
What has the least mass in an atom?
Electrons have the least mass in an atom. They are much lighter than protons and neutrons.
What part of the atom does not add mass to it?
The electron.
What stable particle found in an atom has the least mass?
the electron
