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
What else can I help you with?
What is the mass number of an atom equal to?
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.
What is the sum of protons and neutrons in an atom?
Mass number!:)
What equals the number of neutrons plus the number of protons in an atom?
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.
Which atom has an average mass not equal to its common isotope?
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.
What is the number of sulfur atoms that equal a mass of 32.07 amu?
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 mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the symbol "A."
What is atomic mass of an atom equal to?
The atomic mass of an element is equal to the number of protons.
What is the mass number of an atom equal to?
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.
What is the mass number of atom equal to?
proton
What does the atomic mass number an atom tell you about the atom?
The mass number of an atom is equal to the sum of its number of protons and neutrons, simply, nucleons.
What does the atomic mass number of an atom tell you about the atom?
The mass number of an atom is equal to the sum of its number of protons and neutrons, simply, nucleons.
The atomic mass of an atom is equal to?
the total mass of its protons, neutrons, and electrons.
The mass number of an atom is equal to what?
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.
Does the mass of one helium-4 atom equal one atomic mass unit?
The mass of a helium-4 atom is 4,002 602 amu.
Is the mass number of an atom equal to the atomic number?
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.
As we know that 1amu not equal to mass of 1 proton then why protium is equal to 1amu?
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.
Why doest the atomic number equal the atomic mass?
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
