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.
Which sub atomic particles cause isotopes to appear?
Isotopes are caused by variations in the number of neutrons in an atom's nucleus. Neutrons are subatomic particles that do not carry an electric charge and contribute to an atom's mass. The different number of neutrons in isotopes result in variations in atomic mass.
What particles contributing to the atomic mass?
protons and neutrons
Is atomic mass and molar mass similar and mass number of particles the same?
Atomic mass and molar mass are similar concepts but not the same. Atomic mass refers to the average mass of an atom of an element, while molar mass is the mass of one mole of a substance. The mass number of particles can be the same in certain cases, such as isotopes of the same element which have the same number of protons and different numbers of neutrons.
What is the atomic particle that has an extremely small mass compared to the others?
Of the 3 atomic particles protons, neutrons and electrons, electrons have the smallest mass.
What is the unit for the mass of atomic particles?
Atomic Mass Unit (amu)
What is the unit of measurement use for atomic particles?
Atomic mass unit

Si units used for the masses of atomic particles?
The atomic mass unit (u) or unified atomic mass unit (amu) is the standard unit used to measure the masses of atomic particles such as protons, neutrons, and electrons. 1 atomic mass unit is defined as 1/12th of the mass of a single carbon-12 atom.
What term is used to define the way the mass of subatomic particles is described?
The atomic mass or mass of an atom is locaed at the bottom of a sqaure on the periodic table. The atomic mass= atomic number (protons/neutrons)+electrons. Enable to find the number of electrons you must
What is the mass number of copper?
AMU (Atomic Mass Unit) is the SI masses of particles for nucleus.
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.
What particles contributing to the atomic mass?
protons and neutrons
Relation between subatomic particles and atomic mass unit?
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
Which subatomic particles have mass and re included in the calculation of the atomic mass number?
Protons and neutrons are the subatomic particles that have mass and are included in the calculation of the atomic mass number. Electrons have very low mass compared to protons and neutrons and are usually not included in the atomic mass calculation as they contribute very little to the overall mass of an atom.
Which term is used to describe the way the mass of subatomic particles is described?
Atomic Mass units =]
