It looks like you have combined two concepts. The number of protons in an atom is the atomic number. The sum of the protons and the neutrons in an atom is the mass number. There is no such thing as an Atomic Mass number.
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 number of protons, electrons, and neutrons:P
The sum of the number of protons and the number of nuetrons.
the total number of protons and neutrons 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 Atomic Mass is equal to the number of protons and electrons that an element has.
The mass number = protons + 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.
no, the mass number is number of protons in an atom, plus the number of neutrons.
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.
the total number of protons and neutrons in the nucleus.
