Atomic Mass/ Structure
Cards in this deck (5)
- 1Relative Atomic StructureRelative atomic masses (Ar) is the mass of a given element, with values taken from the periodic table.
- 2Relative FormulaRelative formula masses (Mr) is the combined mass of all element in a chemical forumla.
- 3IsotopesIsotopes are atoms of an element with the same number of protons, but a different number of neutrons.
- 4Working Out(iso 1 x ab 1) + (iso 2 x ab 2)

iso = isotope
ab = abundance - 5Examples(35 x 75) + (37 x 25) = 35.5

(12 x 98.93) + (13 x 1.07) = 12.01
