What sub-atomic particles make up the atomic mass?
The atomic mass of an atom is primarily made up of protons and neutrons, which are collectively known as nucleons. Protons, positively charged particles, and neutrons, neutral particles, reside in the nucleus of an atom. Electrons, which are negatively charged, contribute negligibly to the atomic mass due to their much smaller mass compared to protons and neutrons. Thus, the atomic mass is largely determined by the number of protons and neutrons in the nucleus.
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.
What two particles of the atom are added together to get the atomic mass?
4
What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
What particles make up the mass of an atom?
The number of protons
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
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.
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.

Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
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)
What the distinction between atomic mass and atomic number?
the number of positive charges or protons in the nucleus of an atom of a given element, and therefore also the number of electrons normally surrounding the nucleus. (atomic number) The mass of a given atom or molecule, expressed in atomic mass units. (atomic mass)
