What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
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.
Have about 1800 times less mass than protons and neutrons?
Electrons have ~1800 times less mass than protons and neutrons
What is the mass of an atom that has 92 protons and 108 neutrons?
If you have 92 protons and 108 neutrons you will get 200 electrons
What is pair of particles with nearly the same mass?
Protons and neutrons have near identical mass. One will not have to account for the difference in mass in most calculations.
What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
What Make up nearly all of an atoms mass?
The sum of all protons and neutrons - Apex Learning
What particles make up the mass of an atom?
The number of protons
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
Which subatomic particles of an atom are responsible for atomic mass?
Protons and neutrons are responsible for the atomic mass of an atom. Protons have a positive charge, while neutrons have no charge. The combined mass of protons and neutrons makes up the majority of the mass of an atom.
What is the sum of protons neutrons in an atom?
Mass number = Protons+Neutrons
What is the mass of an atom with 13 protons and 14 neutrons?
The mass of an atom is primarily determined by the sum of its protons and neutrons. To find the mass of an atom with 13 protons and 14 neutrons, add the total number of protons and neutrons together: 13 protons + 14 neutrons = 27. The approximate mass of this atom would be 27 atomic mass units (amu).
Which subatomic particles are closest in mass?
Protons and nuetrons Dom says: Protons and Neutrons.
What is the sum of protons and neutrons in an atom?
Mass number!:)
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
What determines the mas of an atom?
The mass of an atom is determined by the combined mass of its protons, neutrons, and electrons. Protons and neutrons are the primary contributors to the mass, while electrons have a negligible mass in comparison.
