The mass of an atomic nucleon is approximately 1 atomic mass unit (u) or 1.66 x 10^-27 kg. This value is commonly used as a reference unit for expressing the masses of atomic particles such as protons and neutrons.
The atomic mass number represents the total number of protons and neutrons in an atom's nucleus. It does not include the electrons because their mass is negligible compared to protons and neutrons.
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
Proton and neutron.
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit

These particle are neutrons and protons; they are located in the atomic nucleus.
Protons and neutrons, both residing in nucleus
Protons, neutrons and electrons.
Ah, isn't it fascinating how the proton and neutron have about the same mass? They're like two peas in a pod, working together to make up the nucleus of an atom. Just imagine them dancing around, creating harmony in the world of particles.
An alpha particle has 2 protons and 2 neutrons. This would make the atomic number decrease by 2 and the Atomic Mass will decrease by 4.
The mass of an atomic nucleon is approximately 1 atomic mass unit (u) or 1.66 x 10^-27 kg. This value is commonly used as a reference unit for expressing the masses of atomic particles such as protons and neutrons.
Alpha particles are a type of nuclear radiation with a mass of 4 atomic mass units. They consist of two protons and two neutrons bound together.
The atomic mass number represents the total number of protons and neutrons in an atom's nucleus. It does not include the electrons because their mass is negligible compared to protons and neutrons.
Protons and neutrons make up the mass. They are present in nucleus.
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
