isotope

isotope. Are atoms of the same element that have different masses. Due to a different number of neutrons in the nucleus. Nuclide. Is a general term for any isotope of any element. Atomic number. Represented in mathematical equations by the letter Z in the book examples.

Atomic Mass

Atomic Mass. What is an appropriate unit for measuring the mass of a single atom?. A Gram is much too large 1 Oxygen atom = 2.65x10 -23 g !! A new standard was chosen Atomic mass units (amu) 1.00amu = 1.66x10 -24 g. Atomic mass units .

Subatomic Particles

Subatomic Particles. Calculating Average Atomic Mass. expressed in atomic mass units (amu) done because actual masses so small and hard to work with based on carbon-12 assigned mass of exactly 12 amu weighted average of all naturally occurring isotopes.
