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.
What part of the atom is the heaviest has the most mass?
The nucleus of an atom is the heaviest part and contains most of the atom's mass. It is made up of protons and neutrons. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.
What subtomic particle account for most all of an atoms mass?
Protons and neutrons, which are found in an atom's nucleus, account for most of an atom's mass. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.
The nucleus of a helium atom is called?
The nucleus of a helium atom is called an alpha particle. The electromagnetic waves emitted by a nucleus are called gamma rays.
Where can most of the mass in an atom be found?
Most of the mass in an atom can be found in the nucleus, which houses the protons and neutrons. Protons and neutrons are much more massive than electrons, which orbit the nucleus in the electron cloud.
What represents most of an atom's mass?
The nucleus of an atom represents most of an atom's mass.
The mass of an atom compared to the mass of a carbon-12 atom is called the?
Isotope.
The center of an atom where the neutrons and protons exist?
That is called the nucleus. It is positively charged and it makes up most of the atom's mass.
What makes up most of the mass of Atom?
protons and neutrons make up most of the mass in an atom
What makes up most of the mass of an atom?
protons and neutrons make up most of the mass in an atom
What is the total mass of the protons and neutrons in an atom called?
The total mass of the protons and neutrons in an atom is called the atomic mass or mass number. It is often represented by the symbol A.
Where is the most mass in an atom concentrated?
in the nucleus of the atom
What do we call the tiny core at the center of an atom containing most of the atom's mass and all if its positive charge?
The core at the center of an atom is called the nucleus. It contains protons, which have positive charge, and neutrons, which contribute to the mass of the atom.
Where is most of the mass located in the helium atom?
Most of the mass in a helium atom is located in its nucleus, which contains two protons and usually two neutrons,forming a total of four particles called nucleons. The electrons only contribute a small fraction of the atom's overall mass.
Where is the mass in atom?
Most of the mass in an atom is found in the nucleus, which contains the protons and neutrons.
Most of the mass of an atom is concentrated in the?
in the nucleus of the atom
The region in an atom that contains most of the mass is called?
Most of the atom's mass is concentrated in the nucleus.
