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 are the two parts of the atom that have a mass of 1 atomic mass unit?
The two parts of the atom that have a mass of approximately 1 atomic mass unit (amu) are protons and neutrons. Protons are positively charged particles found in the nucleus of an atom, while neutrons are neutral particles that also reside in the nucleus. Together, these particles make up the majority of an atom's mass. Electrons, on the other hand, have a negligible mass compared to protons and neutrons.
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.
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.
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
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?

What sub atomic particles makes up mass of an atom?
Protons and neutrons
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)
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
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)
Which term is used to describe the way the mass of subatomic particles is described?
Atomic Mass units =]
Does an atom of aluminum and an atom of gallium have the same atomic mass?
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
