Reductionists approach reduces the size of everything in order to break down and understand what"s happening. Wholist approach feels everything has to be together as a whole in order to understand how things are happening. Smallest unit of matter separable by normal chemical means. The smallest unit of matter that retains all of the properties of that element. Atomic mass mass of all subatomic particles/number of protons and neutrons ( electrons have zero mass) The number of electrons that need to be gained or lost to fill the outer shell of electrons. Form when atoms gain or lose or share electrons. They are the result of electrical attractions between the atoms. Form when atoms completely gain and lose electrons. Bond between sodium and chlorine is the standard example. Increase as we go from left to right across the periodic table. When difference is 1. 7 or greater the bond is usually ionic. When the difference is between 0. 5 and 1. 7.
