The relative atomic weight or standard atomic weight (not mass) of a chemical element is the ratio between the average mass of the atoms of this element to 1/12 from the Atomic Mass of carbon-12.

The Atomic Mass is a value denoting the total mass of all the protons, neutrons, and electrons in an isotope.

The atomic weight (not mass) of a chemical element is the ratio between the average mass of the atoms of this element to 1/12 from the atomic mass of carbon-12.

The atomic mass is a term applied only to specific isotopes; the unit is the same as above.

The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.

The atomic number, on the other hand, tells us how many protons are in the nucleus of an atom.

IUPAC publish periodically tables of atomic weights - the last edition is from 2009-2010.

For the atomic masses of isotopes the last published edition is The AME 2003 atomic mass evaluation, edited by Audi, Wapstra and Thibault.

The mass spectrometer tells us the ratio of mass to charge in a sample. If we know the charge, then we can determine the mass. If we know the mass, then we can determine the nature of the content, in terms of elements.

How do you find the chemical element of an atom?

If you know how many protons the atom has, then that can tell you what element from the periodic table is classifying the atom.


What atom has the mass number of 25?

Knowing the nuclear charge of an element is important as it will tell you what kind of reactions you can expect. The element with the nuclear charge of 25 is manganese.


How can you tell silver from tin?

Although all metals have a similar metallic appearance, it is possible to identify silver by its unusually whitish luster. Tin is a darker shade of gray. There are also chemical tests that you can use, but it shouldn't be necessary. There is an instrument called a mass spectrometer which can be used to identify any element with remarkable accuracy.


How can the number of neutrons in an atom be determined?

1. Locate the element on the periodic table.2. Find the element’s atomic number (which is the same as the number of protons)3. Find the element’s atomic weight.4. Round off the atomic weight to the nearest whole number to find the atomic mass.5. Subtract the atomic number from the atomic mass (The numbers after the decimal point represent the usually very small mass of the electrons in the atom.)


What does the number of protons in an atom also tell you?

The number of protons in the nucleus of an atom tell you which element you are dealing with. It is the number of protons in an atomic nucleus that determines the elemental identity. Only that. The atomic number of an element is the number of protons you will find in the nucleus of every atom of that element, regardless of the number of neutrons or electrons involved.

What can the atomic mass tell you about an atom?

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.


How do scienctist tell the difference between two isotope of the same element?

Isotopes of the same element are determined based off the number of neutrons the atom has which is directed related to the atomic mass of the element( the more neutrons the greater the mass of that atom). Because you can not change the number of protons in an atom without changing the element, scientist differentiate isotopes based off the atomic mass of the isotope.


What does the atomic mass tell you about a atom?

The mass.If you also know the element number you can figure out the number of neutrons (provided its an isotopic mass rather than an average mass).


What the atomic mass tell the total number of?

The Atomic Mass of an element tells you what the mass of one mole (6.022 x 1023 atoms) of the element is. It sort of tells you the number of protons & neutrons in the atom, but that is not necessarily precise.

What does an element's mass number tell us?

How do you tell the number of neutrons in an element?

Subtract the atom number from the mass number to get the neutron. Mass number is the sum of neutrons and electrons. Atom number is the number of electrons. the number of electrons is equivalent to the number of protons.
