background image CHM1046 Exam One Study Guide Dr. Cameron’s Lecture 1) Bonding a) Ionic: transfers/gives an electron from one  element to the other; ex: Na+ and Cl- b) Covalent: want to share a pair of electrons; ex: Cl and Cl c)Polar Covalent: share electrons, but create a  polar dipole i) ex: C and F, creates a dipole making C a little bit positive and F a little bit negative 2) Electronegativity a) Is the power of an atom to attract electrons b) Polar Covalent: change in electronegativity  greater than 0.4 c)Covalent: if the change in electronegativity is  less than or equal to 0.4 d) C-H Bond is nonpolar (change is = 0.4) 3) Lewis Structures  a) Count up the # of electrons for each  element in the compound; add all together b) Divide total # of electrons in the compound by 2 to get the number of pairs of electrons 
(*or “things” as Dr. Cameron says)
c)Draw Lewis Structure and make sure you have  the correct number of bonds and electrons.

compound. 
4) Geometries Three “Things” Trigonal Planar Bent Four “Things”     Tetrahedral Trigonal Pyramid Bent Five “Things”

but all of them count for molecular geometries
b) “Things”: number of electrons or elements  that the central element is bonded to c)With tetrahedral shape, different angles make  it to where the dipoles to do not actually line 
up and cancel
