Step 1 of 3

Friday, September 16, 2016 Week 3 Notes CHE 152 - Ions and the periodic table for main group elements: • - metals lose electrons (until they have the same number of electrons as the nearest noble gas) and become cations - nonmetals tend to gain electrons (until they have the same number of electrons as the nearest noble gas) and become anions • an atomic mass unit (amu) is exactly 1/12 the mass of a carbon-12 isotope • isotopic mass: the mass of a given isotope - the mass number =/= the mass on the periodic table (atomic mass) this is because the atomic mass is the weighted average of the isotopes of a • given element. found by taking the sum of iso
