In Bohr's model which particles make up the most mass of the atom?
the electron particles make up the mostr mass
How many total number of particles present in one atom?
The answer depends on the atom! The total number of subatomic particles in an atom of an isotope is the sum of the mass number and the atomic number of the isotope; the mass number counts the protons and neutrons together, and the atomic number recounts the number of protons, which in a neutral atom must be the same as the number of protons.
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
What particles make up the mass of the atom?
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.
Which particles in an atom contribute most to mass of the atom?
The particles are protons, neutrons, and the nucleus inside of the atom Nice helping u >_<
What two particles of the atom are added together to get the atomic mass?
4
What particles are added together to determine atomic mass?
The number of protons, neutrons and electrons.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
What two subatomic particles are added together to determine the mass number?
Protons plus the neutrons
What two subatomic particles are added together to calulate the atomic mass?
Protons, neutrons and electrons.
What do you add together to get an atoms mass?
The protons and the neutrons, because those are the only particles in the atom that contain quarks.
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
Which particles in a atom have a mass of 1?
protons and nuetrons
What subatomic particle or particles contributes the most to the mass of the atom?
These particles are protons and neutrons.
How many total number of particles present in one atom?

The total number of subatomic particles in an atom of an isotope is the sum of the mass number and the atomic number of the isotope; the mass number counts the protons and neutrons together, and the atomic number recounts the number of protons, which in a neutral atom must be the same as the number of protons.
In Bohr's model which particles make up the most mass of the atom?
the electron particles make up the mostr mass
What particle or particles carry virtually all the mass (weight) of any atom?
Virtually all of the mass of an atom is carried by the proton and the neutron. The electron has very, very little mass relative to these two particles.
