What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an atom is the sum of its protons and neutrons. It represents the total number of nuclear particles (protons and neutrons) in the atom's nucleus. The number of protons in an atom determines its element, while the number of neutrons can vary to create different isotopes of the element.
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 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 neutrons in an atom?
Mass number = Protons+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.
