Where is most of the atoms mass found?
An atom's mass is concentrated in its nucleus, which is located in the center of the atom. Protons and neutrons within the nucleus are responsible for its mass; the electrons, which are located outside of the nucleus, don't contribute to the mass of the atom.
What is in the center of the atom?
Nucleus. Composed of Protons and neutrons. Can be sub-divided further but you probably don't have to know that. (quarks and muons and such.)
What contributes to the mass of the atom?
number of protons and number of neutrons
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
What is an atom's mass number?
The sum of the protons and neutrons in the nucleus
Is mass located in an atom's nucleus or in its protons?
The mass of an atom is concentrated in the nucleus, which is made up of protons and neutrons.

Where are protons found in the nucleus of an atom?
Protons, and neutrons make up the nucleus of an atom. The nucleus is the centre of an atom where most of the mass is found. Protons are positively charged, neutrons have no charge.
What is the purpose of nucleus in an atom?
The nucleus of an atom is the central part of an atom containing practically all the mass of the atom. The nucleus is composed from protons and neutrons.
What part of the atom contains most of its mass?
The nucleus, made up of protons and neutrons, contains most of an atom's mass.

What contributes to the mass of the atom?
number of protons and number of neutrons
What does the mass of an atom depend on?
The number of neutrons and protons in the nucleus of the atom.
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
Where is the mass in atom?
Most of the mass in an atom is found in the nucleus, which contains the protons and neutrons.
What is the atomic mass of an atom?
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
Sum of protons and neutrons in the nucleus of an atom?
mass number
