Why is most of the mass of an atom found in its nucleus?
Most of the mass of an atom is found in its nucleus because the nucleus contains protons and neutrons, which are much heavier than electrons. Protons and neutrons have approximately the same mass; together they account for almost all of the mass of an atom. Electrons contribute very little to the overall mass of an atom.
Where is most of the atoms mass found?
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.
Where is all the mass of an atom concentrated in?
The mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. The nucleus is extremely small compared to the overall size of the atom, but it contains almost all of the atom's mass. Electrons, which are much smaller in mass, orbit around the nucleus.
The mass of all particles of an atom added together is its what?
The sum of protons and neutrons in an atom is called mass number.
Where is the most mass of an atom?
Almost all of the mass of an atom is in the nucleus. The nucleus is made up of protons and neutrons, with hydrogen-1 as the lone exception because its nucleus has only a proton in it. In other atoms, protons and neutrons are fused together to form that nucleus. The electrons are out in their electron cloud. And we mention the electron because it has only about 1/1836th the mass of a proton. See how it works? A fistful of electrons weigh almost nothing compared to a single proton. The neutron is slightly heavier than a proton, so when neutrons and protons are gathered in any atomic nucleus, it contains most all of the mass of that atom.
What is nearly all of an atom's made up of?
Nearly all of an atom and mass is made up of protons and neutrons.
Contains nearly all the mass of the atom?
the nucleus
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.
What is nearly all of an atoms mass made up of?
Nearly all of an atom and mass is made up of protons and neutrons.
Which part of an atom make up nearly all the mass of an atom?
This would be the NUCLEUS.
Made up of the protons and neutrons this part of the atom contains nearly all the mass of the atom?
The nucleus is the part of the atom made up of protons and neutrons, and it contains nearly all of the atom's mass. Electrons, which have much lesser mass, orbit around the nucleus.
Where does majority of a atoms mass come from?
Very nearly all of the mass of an atom is found in the nucleus in the form of Protons and Neutrons. Electrons and "binding energy" contribute a tiny amount of additional mass.
What makes up nearly all of atom mass?
The nucleolus.
What makes up nearly all of the atom's mass?
The sum of all Protons and Neutrons.
What do you think the majority of an atom is made of?
Nearly all the mass is in the nucleus; however, the bulk of an atom's volume is empty space.
what makes nearly all of the atom's mass?
The nucleolus.
Where can the most mass be found in an atom?
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.
