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.
Mass 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.
in order to obtain the mass number of an atom you must get the number of neutrons + the number of protons which = the mass number !!!hope this helped!!! :)
Its the mass number of an atom.The mass of an atom is concentrated in the nucleus. Both protons and neutrons which are collectively known as nucleons are found within the nucleus.Mass of electrons are not considered to be contributing towards the mass no. of an atom as their size is small and thus their mass is negligible.
One sulfur atom has an atomic mass of 32.07 amu. Therefore, to find the number of sulfur atoms that equal a mass of 32.07 amu, you would need just one sulfur atom.
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the symbol "A."
The mass number of an atom is equal to the sum of its number of protons and neutrons, simply, nucleons.
The mass number of an atom is equal to the sum of its number of protons and neutrons, simply, nucleons.
Only if the atom is hydrogen-1! The mass number of the atom is equal to the sum of the numbers of protons, which is the same as the atomic number, plus the number of neutrons. The only non-radioactive atom without neutrons is hydrogen-1.
proton
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the letter "A" in the chemical symbol notation, where A = number of protons + number of neutrons in the nucleus of the atom.
The atomic mass of an element is equal to the number of protons.

Mass 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.
It is equal to the difference between atomic number and Atomic Mass number. A+
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
