Which sub atomic particle makes up most of the mass of atom?
These particles are proton and neutron.
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 subatomic particles of an atom are responsible for atomic mass?
Protons and neutrons are responsible for the atomic mass of an atom. Protons have a positive charge, while neutrons have no charge. The combined mass of protons and neutrons makes up the majority of the mass of an atom.
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?
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.
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.
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)
