it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
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. Is a value denoting the total mass of all the protons, neutrons, and electrons in an isotope.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.
It tells you the average amount of protons and neutrons within the nucleus of an atom. In other words, atomic mass - atomic number (protons)= the number of neutrons within the nucleus.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
Cobalt is an atomic mass of 58.93 atomic mass units
Type your answer here..The Atomic Mass Unit tells us that ,How heavy a substance as compare to the other.
atomic mass is the no. of protons+no. of nuetron
The periodic table is in order of atomic mass
Atomic number tells the number of protons and electrons, but i don't remember for atomic mass.
The Atomic Mass of an element tells you the average mass of an atom in the element.
Atomic Mass is the no. of protons+no. of nuetron

None. The relative abundance of isotopes is used to calculate the Average Mass (by multiplying the Atomic Mass of the isotopes by their relative abundancies and adding the products together) while the Atomic Mass is simply the number of protons plus the number of neutrons.
