11 Chap 4 Chemical Bonding 05 Lewis Dot Structure In both cases lewis dot structures were used to visualize the the bonding of the atoms in case of electron sharing or electron transfer. basic lewis dot structures there are two basic types of bonding that form the basis of the lewis theory and it is important to understood before one can begin to draw lewis dot structures. A lewis structure includes lines for covalent chemical bonds and dots for valence electrons or lone electron pairs. different ways to draw lewis structures. there is more than one “right” way to draw a lewis structure. if you are drawing the structures for a chemistry class, be sure to know what your instructor expects. General terms for lewis dot structures: 1. dot • one dot represents one valence electron (found on odd electron particles) 2. pair of dots •• a pair of dots represents a nonbonding (lone) pair of electrons that are not involved in a covalent bond and "belong to" only one atom. 3. For anions add a number of electrons equal to the negative charge. for cations subtract a number of electrons equal to the positive charge. 4. place one electron pair between each pair of adjacent atoms (as determined from the framework found in step 2) to form a single bond. 5.

Step 1: figure out how many electrons the molecule must have, based on the number of valence electrons in each atom. when drawing the structure of an ion, be sure to add subtract electrons to account for the charge. step 2: connect the atoms to each other with single bonds to form a “skeleton structure.”. Lewis structure, also known as lewis dot structure or electron dot structure, is a simple and straightforward way of representing the outermost electron shell in a chemical species like an atom, ion, or molecule. it shows how electrons are positioned around the atoms either as lone pairs or in a chemical bond, typically a covalent bond or a.
