Protons and neutrons make up almost all the mass of an atom. Consider that the proton is about 1836 times more massive than an electron, and that the neutron is slightly more massive than the proton, and it becomes crystal clear.

What two particles of the atom are added together to get the atomic mass?
4
Do carbon and oxygen have the same atomic mass?
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
Nitrogen has an atomic mass of 14 and an atomic number of 7 so the number of neutrons must be?
The atomic mass of an atom is the total mass of its particles. The atomic number is the number of protons in the atom's nucleus. To find the number of neutrons in an atom, we take its atomic mass (the total mass of its particles) and subtract its atomic number (the number of protons and electrons in the atom). A: Lithium has an atomic mass of 7 and an atomic number of 3 so the number of neutrons is equal to 4. (7 - 3 = 4)
Is atomic mass and molar mass similar and mass number of particles the same?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Can you identify an atom without knowing number of neutrons in it?
Yes, and in order to find the Number of Neutrons, subtract Atomic Mass from Number Of Protons, the result will be the Number of Neutrons for that atom *No. Of Neutron=Atomic Mass - Number Of Protons
How do you determine the numbers of the three types of particles in each atom?
In an atom, no. of protons = no. of electrons=atomic no. no. of neutrons=atomic mass-atomic no.
What are the particles that make a atom including the atomic number and mass number?
The atomic number is the number of protons in an atom (which equal the number of electrons present) The atomic mass is the number of protons+neutrons in an atom

What sub atomic particles makes up mass of an atom?
Protons and neutrons
The mass of all particles of an atom added together is its what?
The sum of protons and neutrons in an atom is called mass number.
Is atomic mass and molar mass similar and mass number of particles the same?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.

What does the mass of an atom consist of?
the mass of an atom is concentrated in a very small central portion of the atom which is called the atomic nucleus. The atomic nucleus is made up of nucleons, of which there are two important fundamental types: electrically positive protons and electrically neutral neutrons. So the Answer for the question is: Neutrons and Protons.
Which sub atomic particle makes up most of the mass of atom?
These particles are proton and neutron.
Would you use atomic number or mass number or both to obtain the number of particles in an atom?
atomic number is the total number of protons OR electrons in an atom. mass number is the total sum of number of protons and neutrons. atomic number subtracted from mass number gives the number of neutrons in an atom. Mass number - atomic number = number of neutrons.
