Unformatted text preview: Ch 4 Notes 1. Fonic and covalent Bonds - consist of cations formed from metallic elements and anions formed from nonmetaliionic bonds of opposite change Pheld together by electrostatic attractions between ions energy .strength of these attrachions is a form of potential electrostahic potential energy (Bel), also called coulombic attraction The value of Fel is directly proportional to the product of their charges (Q1 and Q and inversely proportional to the dBtance (dl) between their vuclei . we can turn this expression into something more applicable Eet = 2.31*10-14 Jinm (Q, *Q2|| - when two atoms share 2 their electrons equally:covalent bones > bond length depends on the bond and atom .bond strength or bond energy is the amount of energy required to break one mole of molecules o 2. Naming Compounds and Waiting Formulas Tonic compounds of Main Group Elements > Bincin . binary two-element ionic compounds' contain acation from a group 1 luerelement and an enten formed by a group 15-17 element . there are only the rules' for naminer them Reminder: they have two word names ds anchos et compoundI The first word is the name of the cation which is simply the name of its parent element 2 The second word is the name of the anion, which is the name of its parent element with the ending changed to ide o when translating the name of a binary Tonic compound into a formular the positive and negative charge of the nons and anyos nams Be in balance Binay tonic compounds of Transihan Metals some metallic elements including many transthon metals, form mulhple eations with crterent changes to fix this, a Roman numeral after the name of the transition metal to indicate the positive charge on the metal's con another alder method is to use historical names to identity different cations of the same element u -new method: copper (ID oxicle is Cul copper oxide is Curl -old method cuprous ion is cut -note that for the old me thod, theion with the lower charge ends in cous and the name of the ion with the higher charge ends in fic is used cupac ion is Cu2+> Polyatomic loos -generic formula xom .meny polyatomic anions are exoanions .an oxuanian's name is based on the in its formula with that element element x that appears before oxygen enclina changed to either ite occate - enching in cate oxo union of an element than its site oxoanich has a larger number of oxygen atoms OXO anions add prefixes if an element forms more than two -oxo anion with greatest number of oxygen -ale atoms has the prefix per- and endin -oxo anion with fewest exygen atoms has prefix hypo- and endly invite -> Binary Molecular compounds .forms with two non metals I The first word is the name of the first element in the formula 2. For the second word change the ending of the name of the second element to -ide 3. Use prefixes to indicate the number of atoms of each type in the molecule, but do not use the prefix mono- with the first element in a name . when prehixes ending in 0.- era precedea name that begins with a vowel, the o- or a- is deleted to make the mew wore! easier to pronounce
