The mass of an atom is contained primarily in its nucleus.
nucleus!
most of the mass is contained in the nucleus.the mass is spread evenly through the whole atom, and the electron cloud.
When calculating the mass of an atom, you add the mass of the protons and the neutrons. This is the nucleus of the atom. The electrons are small enough to be ignored except in the most delicate calculations.
An atom's mass is concentrated in its nucleus, which is located in the center of the atom. Protons and neutrons within the nucleus are responsible for its mass; the electrons, which are located outside of the nucleus, don't contribute to the mass of the atom.
Mass of an atom = Mass of proton + Mass of neutron
No. On average a sulfur atom is twice the mass of an oxygen atom.
Within the atom's nucleus.
Protons and neutrons. Virtually all of the atom's mass.

Since the Earth is not a single atom, nor a collection of similar atoms, it does not have an atomic mass. Atomic mass is a measure of how much matter is contained by a specific atom.

Yes. because electrons revolve around the nucleus and have practically negligible mass when compared to the nucleus.
Proton: positive charged particle, contained in atomic nucleus, mass=approx. 1 u Neutron: neutral particle, contained in atomic nucleus, mass=approx. 1 u Electron: negative charged particle, component of an atom (but not contained in nucleus), mass=approx. 1/1836 from the mass of a proton.
They differ by mass, electrical charge, dimensions, location in atom, type of qurks contained.
Named for the famous chemist Ernest Rutherford who improved on the "plum pudding" model of the atom by postulating a nucleus which contained most of the atom's mass.
99.9% of it. And unless you are talking a "Single Atom" Everything is Mass, Until the Illusive "Absolute" proves otherwise.
5 valence electrons can be contained in 1 atom
