What particles make up the mass of an atom?
The number of protons
What contributes to the most of the mass of an atom?
The majority of the volume in an atom is filled by the neutrons and the protons. Although the electrons do have a volume, they occupy significantly less space than the other two subatomic particles
What is determined the mass of an atom?
Protons, neutrons and electrons
What can be determined by looking at the atomic number of an element?
the number of protons in an atom and the number of electrons in an atom
Is An atom's atomic mass is the total mass of all of its electrons and protons?
Yes
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
How are electrons and protons related?
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons

Is the mass number the sum of electrons and protons in the atom?
No electrones have no mass
All of the mass of an atom is due to the?
The mass of an atom is the sum of the masses of protons, neutrons and electrons.
The diameter of an atom is?
in the bottom Atomic nucleus is at the center of the atom.
How are protons and neutrons related?
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
Does an atom has mass?
Yes, atoms are made up of protons, neutrons, and electrons. Protons are neutrons each weigh 1 Atomic Mass unit (amu). Electrons weigh about 1/1836 of an amu and don't really contribute to the weight of an atom at all. The more protons and neutrons an atom has the more it weighs.
What can be determined by looking at the atomic number of an element?
the number of protons in an atom and the number of electrons in an atom
