In Bohr's model which particles make up the most mass of the atom?
the electron particles make up the mostr 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 account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
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.
Which particle has the least mass and where is this particle located in the atom?
The smallest particles that have been discovered and that don't only exist in theory are the quarks. They are what make up protons, neutrons, all kinds of baryons, and a few other categories of particles. But there is a theory of smaller particles that make up quarks, electrons, and other particles that were previously believed to be fundamental (But, again, these particles only exist in theory). These particles are to be called "rishons" if discovered.
In Bohr's model which particles make up the most mass of the atom?
the electron particles make up the mostr mass
What particles make up most of the mass atom?
air,mater
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 particles take up most of the mass of an atom?
Protons and neutrons make up most of the mass of an atom. Electrons weigh almost nothing by comparison.
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
Which two particles make up most of the mass of a C-12 atom?
proton and neutron
What are the particles that make a atom including the atomic number and mass number?
The atomic number is the number of protons in an atom (which equal the number of electrons present) The atomic mass is the number of protons+neutrons in an atom
Which particles in a atom have a mass of 1?
protons and nuetrons
Which subatomic particles makes up most of the mass off the atom?
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
What subatomic particle or particles contributes the most to the mass of the atom?
These particles are protons and neutrons.
Which two subatomic particles make up the atomic weight of an atom of an element?
The protons and the neutrons make up the atomic weight of an atom of an element, they have roughly the same mass and electrons have so little mass that they're negligible.
