What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
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.
Which particle or particles of an atom have little mass?
electrons
How do you determine the numbers of subatomic particles in an atom based on its identity?
Atomic number of a chemical element = Number of protons = Number of electrons Atomic mass of an isotope (mass number) - Number of protons = Number of neutrons
What two particles of the atom are added together to get the atomic mass?
4
How do you determine the numbers of the three types of particles in each atom?
In an atom, no. of protons = no. of electrons=atomic no. no. of neutrons=atomic mass-atomic no.
What is counted in an atom to determine mass number?
NEUTRONS AND PROTONS are counted in an atom to determine it's mass number.
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
How do you determine the atom the atomic mass of an atom?
Proton + Nuetron = Atomic Mass
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.
In Bohr's model which particles make up the most mass of the atom?
the electron particles make up the mostr mass
How do you determine an atom's mass number?
mass number= no. of protons + no. of neutron

Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
What are the two particles that makeup the mass of an atom?
protons and neutrons
