The total number of subatomic particles in the nucleus
atomic mass unit is equal to one-twelfth of the mass of a carbon-12 atomic mass is equal to one-twelfth of the mass of a carbon-12Atomic Mass is equal to the number of protons and neutrons.
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the symbol "A."
The atomic mass of an element is equal to the number of protons.
The mass number = protons + neutrons
The Atomic Mass is equal to the number of protons and electrons that an element has.
no, the mass number is number of protons in an atom, plus the number of neutrons.
The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
The number of protons, electrons, and neutrons:P
The sum of the number of protons and the number of nuetrons.
The sum of the number of protons and neutrons in an atom is known as the atomic mass. It is equivalent to the mass number of the atom, which represents the total number of protons and neutrons in the nucleus.
