What particles make up the mass of an atom?
The number of protons
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.
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.
How do you calculate the atomic mas based on the number of protons and neutrons of an atom?
To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. Protons and neutrons each have a mass of approximately 1 atomic mass unit (amu). The sum of the protons and neutrons will give you the atomic mass of the atom in atomic mass units.
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?
