the atoms of different elements weigh different.it depends as to which element you are referring to.for example an element with the Atomic Mass 4 can be matched by 2 atoms of a lighter element with the atomic mass 2
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.
Hydrogen atom has an average mass not equal to its common isotope. The most common isotope of hydrogen, hydrogen-1, does not have a neutron in its nucleus, while the average mass of a hydrogen atom accounts for the other isotopes of hydrogen which do contain neutrons.
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 atomic mass of an element is equal to the number of protons.
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 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.
the total mass of its protons, neutrons, and electrons.
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 mass of a helium-4 atom is 4,002 602 amu.
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.
The atomic mass unit (amu) is defined as 1/12 the mass of a carbon-12 atom. It is a unit of mass that is used to describe the masses of atoms and molecules. The mass of a proton is actually slightly less than the mass of a carbon-12 atom, so it is not equal to 1 amu. However, the mass of a protium atom (which is an atom that consists of a single proton and no neutrons) is very close to 1 amu. This is because the mass of the proton makes up most of the mass of a protium atom. Therefore, protium is often said to be "approximately equal" to 1 amu.
atomic mass is contributed mainly by protons and neutrons. it is the mass of an atom. atomic number on the other hand is contributed by protons and is equal to the number of protons in the atom
