Ha ha trick question, you cant do an LDS for an ionic compound

BORONS!!......unless you do the separate LDS’s for the ions P:

What is the proper method for completing Lewis Dot

Structures?

Template byBill Arcuri, WCSD

1. Sum of valence electrons.2. Write symbols for atoms.

3. Connect with single bonds.4. Complete the octets of atoms

bonded to the central atom.5. Place leftover electrons on

the central atom.6. If there are not enough form

a double bond.

Tell a Chemistry joke that makes the class laugh (or even slightly chuckle).

Daily Double!!!

Template byBill Arcuri, WCSD

Why do chemists call helium, curium, and barium the medical elements?

Because if you can’t helium, or curium, you barium. (:
