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 subatomic particles contribute to the atomic mass of an atom?
Protons and neutrons contribute to the atomic mass of an atom. Electrons, despite having mass, contribute negligibly to the overall atomic mass due to their much smaller mass compared to protons and neutrons.
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.
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
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.
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.
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.
What subatomic particles contribute to the atomic mass of an atom?
Protons and neutrons contribute to the atomic mass of an atom. Electrons, despite having mass, contribute negligibly to the overall atomic mass due to their much smaller mass compared to protons and neutrons.
