CHE 110 Lecture Notes - Lecture 9: Single Bond, Triple Bond, Double Bond
Document Summary
Name these: lif = lithium fluoride, no = nitrogen monoxide, they have different rules when naming bc they are different types of compounds (metal and non vs all nonmetals. How many valence electrons do the following have: na = 1, cl = 7, c = 4, h = 1, o = 6. Molecules in random order molecules in random order. Covalent don"t conduct, ionic do if they dissolve in water. !1: ionization energies (how hard it is to rip away electron) and electronegativities (wanting another electron) Electronegativity difference greater than 2. 0 (on average) True for metals and nonmetals: na = 0. 9, cl = 3. 0, difference is 2. 1 so ionic compound. Na: 1, ca: 7: getting to 8 valence electrons, even for the positive one. 8 is full and stable: he and h only go for 2 so they are then full. Covalent bond: 2 atoms share at least a pair of electrons to get to their 8 electrons.
