In Bohr's model which particles make up the most mass of the atom?
In Bohr's model, the most mass of the atom is concentrated in the nucleus, which is made up of protons and neutrons. Electrons, which have significantly less mass, orbit around the nucleus in specific energy levels.
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 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 >_<
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
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.
What particles make up most of the mass atom?
air,mater
Of the three particles that make up an atom which is the lightest?
The electron is the lightest of the three particles that make up an atom, with a mass of approximately 9.11 x 10^-31 kilograms.
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.
In Bohr's model which particles make up the most mass of the atom?
In Bohr's model, the most mass of the atom is concentrated in the nucleus, which is made up of protons and neutrons. Electrons, which have significantly less mass, orbit around the nucleus in specific energy levels.
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
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 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.
The part of the atom that is small and dense is?
The nucleus is the small and dense center of an atom. It contains protons and neutrons, which are the subatomic particles that make up the majority of the atom's mass.
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.
