no,
the mass number is number of protons in an atom, plus the number of neutrons.
false
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 number of neutrons in an atom is equal to the mass number minus the atomic number. The mass number is the total number of protons and neutrons in the nucleus, while the atomic number represents the number of protons. Therefore, the equation can be expressed as: Neutrons = Mass number - Atomic number.
The number of neutrons in an atom is equal to the mass number minus the atomic number. The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number indicates the number of protons. Therefore, the formula can be expressed as: Neutrons = Mass Number - Atomic Number.
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 mass number = protons + neutrons
Mass number!:)
the total number of protons and neutrons in the nucleus.
The atomic mass of an element is equal to the sum of the number of protons and neutrons in its nucleus. It is not directly related to the atomic number, which represents the number of protons in an atom.
mass number
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
It is equal to the difference between atomic number and Atomic Mass number. A+
