Mass of an atom = Mass of proton + Mass of neutron
An atom is comprised of protons, neutrons, and electrons. The electrons take up the most space as they orbit the nucleus. But nearly all of the mass of the atom is found in the nucleus of the protons and neutrons.
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.
No, an oxygen atom does not have twice the mass of a sulfur atom. An oxygen atom has a mass of approximately 16 atomic mass units (amu), while a sulfur atom has a mass of approximately 32 amu. Therefore, a sulfur atom has twice the mass of an oxygen atom.
Its the mass number of an atom.The mass of an atom is concentrated in the nucleus. Both protons and neutrons which are collectively known as nucleons are found within the nucleus.Mass of electrons are not considered to be contributing towards the mass no. of an atom as their size is small and thus their mass is negligible.
Protons and neutrons, the particles that make up atomic nuclei, are the ones responsible for almost all of the mass of an atom. As the electron has less than 1/1800th the mass of a proton, a whole flock of electrons won't significantly change the mass of an atom. We look to the protons and neutrons (called nucleons when they are being considered as components of an atomic nucleus) to contribute to the mass of an atom, and they will be considered when we derive the atom weight of an element.
Most of the mass of an atom is found in the nucleus which contains the protons and neutrons.
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
Most of the mass in an atom is found in the nucleus, which contains the protons and neutrons.
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.
The majority of an atom's mass is found in its nucleus, which is located at the center of the atom. The nucleus is composed of protons and neutrons, which are much more massive than the electrons that orbit the nucleus.

nucleus
The positive charge in an atom is found in the nucleus, which contains protons. Most of the mass of an atom is also located in the nucleus, primarily from the protons and neutrons that make it up. Electrons, which are negatively charged, contribute very little to the mass of an atom.

the electron
Essentially all of the atom's mass is in the nucleus. In the lightest atom, that of hydrogen, it's about 99.95 percent. In the heaviest naturally occurring atom, that of Uranium238, it's about 99.979 percent.
The majority of an atom's mass is found in the nucleus, which contains protons and neutrons. Electrons, which are much smaller in mass, are located in the electron cloud outside the nucleus.
