What particles make up the mass of an atom?
The number of protons
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 number is the atomic mass equal to?
Atomic mass is the number of protons and neutrons in an atom.
How do the numbers of protons, number of neutrons, and the mass number related?
mass no. = no. of protons + no. of neutrons
What two factors determine the atomic mass of an elements?
neutrons and protons
What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
The mass number of an element is equal to the total number of?
The mass number is the average atomic mass of all the isotopes that are found in nature.
What is the sum of protons and neutrons in an atom?
Mass number!:)
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
What is the sum of protons neutrons in an atom?
Mass number = Protons+Neutrons
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
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.
Can protons have twice the mass of neutrons?
No; the mass of proton is similar to the mass of neutrons.
How are protons and neutrons related?
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
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.
