The designation is 1 amu (amu = atomic mass unit). The absolute value of the unit of mass is obtained by dividing the unit by the Avogadro constant NA. The relative mass number of an element thus indicates how many times heavier the atoms of the element are on average than the atomic mass unit.What is atomic mass and how is it determined?
1-The atomic mass number is determined only by the number of nucleons in the nucleus. 2-The atomic mass number is determined only by the number of neutrons in the nucleus. 3-The atomic mass number is determined only by the number of alpha particles emitted.What does the atomic mass tell you?
What does the atomic mass tell us about an atom of an element? The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. It is traditionally represented by the symbol Z. The atomic number uniquely identifies a chemical element.What does Amu stand for?
In physics and chemistry, "AMU" is an abbreviation for atomic mass unit. Sometimes, it is further abbreviated as "u" for unified atomic mass unit. One AMU is the mass of one-twelfth of an atom of the element carbon, isotope 12, and is equal to 1.661 x 10^-27 kilograms. Carbon-12 is used as the base measure...
