the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

Protons and neutrons in the nucleus add up to give the?

The number of protons added to the number of neutrons in a nucleus give that isotope's atomic weight.


What is Nitrogens atomic number and mass and why does it have that?

atomic mass - 14 atomic number - 7 It has that because it has 7 protons (and electrons) = the atomic number. And it also has about 7 neutrons and roughly, the mass number = the number of neutrons+ the number of protons.


What is the mass of the number minus atomic number?

The mass number minus the atomic number is the number of neutrons in an atom. The atomic number is both protons and electrons. Boron, atomic number 5, has two naturally occuring isotopes with mass numbers of 10 and 11, 10B, 11B. The number of neutrons in each is 5 and 6 respectively. The percentage occurence is roughly 20%, 80% respectively. This gives rise to the fractional atomic mass.


How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?

Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.


What is the atomic number for Ag?

Since a single atom is specified, the mass number of the particular isotope that the atom represents needs to be known. The quotient of the mass number and Avogadro's Number will give the approximate mass of the single atom in grams. (For the most accurate answer, the slight difference in mass between a proton and a neutron and the mass of the electrons in the atom will also need to be considered.)

<P>proton + neutrons give you a nucleon. the nuceon(or protons +neutron) give you the overall mass of the atom. the mass of electrons is not included, i dont even think that it has mass at all. Hope you're answered?</P>


What number does the number of protons plus the number of neutrons give you?

The mass number (similar to the Atomic Mass and not to be confused with atomic number) When the number of protons and neutrons is added the result will be its atomic mass or mass number.

Mass number..can be calculated..by the sum of No. of protons and the No. of electrons. And this would give you the the mass number of the element.

What information could you use to determine the atomic number of an unknown element that has the mass number of 22?

To determine the atomic number of an unknown element with a mass number of 22, you would need to know the number of protons in the nucleus of the element. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons from the mass number would give you the atomic number. This is because the atomic number represents the number of protons in an element's nucleus.
