A positively charged ion, also called a cation, is formed when one electron or a few electrons are taken away from an atom. A negatively charged ion, also called an anion, is the opposite: It is formed when one electron or a few electrons are added to an atom.]]> 2018-02-20 12:34:18 UTC https://padlet.com/julia_fagan89/hbo81mik9ekp/wish/233222098 Atoms vs compounds Atoms and molecules in pure substances are chemically combined together julia_fagan89 https://padlet.com/julia_fagan89/hbo81mik9ekp/wish/233222819 2018-02-20 12:37:05 UTC https://padlet.com/julia_fagan89/hbo81mik9ekp/wish/233222819 https://padlet.com/julia_fagan89/hbo81mik9ekp/wish/233223272 Elements are made out of one type of atoms.
