lewis dot structures

lewis dot structures prepared by: richard e. bleil, ph.d. introduction: what can i say? there is more to life than receiving, and more than giving. there is sharing. yep, i'm talking about, of course, covalent compounds. in ionic bonds, one element wants the electron so much more that it literally rips that electron from the valence shell of...

Steps to writing lewis structures

Steps to writing lewis structures dr. yau 1. examine formula to determine whether substance is ionic or molecular. if it is ionic, work with each ion separately. 2. calculate the total # of valence electrons from the group #. remember to adjust for the charge if it is an ion. divide the total by 2 to get # of pairs of valence... ... it also helps to remember that the unpaired electrons in the e-dot symbol of each element... the following examples are organized... draw a lewis structure for...
