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?
Which particle? The electron.
What part of the atom contains the majority of mass an atom has?
The nucleus contains the mass.
What is the smallest part of the atom that has almost no mass?
The smallest part of an atom would be a quark. Quarks are either up or down quarks, and have virtually no mass. Neutrinos have even less mass, but are not part of an atom.
What is the part of the atom that makes up the mass of the atom?
the nucleus of the atom
What element in the universe has the smallest atom?
the atom with the least mass is the hydrogen atom
What part of an atom makes up the mass of an atom?
the nucleus
The neutrons in an atom have the least amount of mass?
No actually, the neutrons and the protons of an atom are relatively the same in mass. Electrons have the smallest mass in an atom, and are not even considered when we look at the mas sof an atom.
What particle found in an atom has the least mass?
the electron
Part of an atom that has least mass?
A high-school answer would probably be the electron. (Of course, maybe you go to an advanced high school?)
Which best describe the nucles of an atom?
It is the part of the atom with the greatest mass
What part of the atom does not add mass to it?
The electron.
