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 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.
mass number
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.
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+
The mass number of an element is equal to the sum of the elements neutrons and protons.
The Atomic Mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
