Lewis Dot Structure Exam 2024 Questions and
Answers 100% Pass
Valence Electrons - ✔✔# of electrons in the highest principle energy level
How to find valence electrons - ✔✔look at ROMAN NUMERAL group number at top of group
Octet Rule - ✔✔all noble gases have 8 valence e. (except hydrogen which has 2 e.)
Lewis Dot Structure - ✔✔Shows how atoms bond in covalent compounds
3 steps to writing lewis dot structure - ✔✔1) add up all of the valence e. 2) determine the central atom 3)
distribute the valence e. so each atom satisfies the octet rule
Central Atom - ✔✔Atom which al of the other atoms are attached to. ANY atom with 2 or more atoms
attached to it
How to find central atom - ✔✔The first atom in the compound, EXCEPT if hydrogen is first (then go to
next atom)
LDS in Ionic Compounds - ✔✔Electrons transfer instead of trying to share (no fighting or sharing)
Atoms need to be connected by at least ____ bond? - ✔✔SINGLE!!!
Never have Different # bonds to the same atom - ✔✔(Resonance)
LDS for ions - ✔✔Do regular LDS but then put a BRACKET around entire LDS
3 exceptions and a twist - ✔✔exceptions- 1) odd number 2) Under the octet 3) Over the octet. TWIST-
resonance
Resonance - ✔✔e. don't belong to either atom but also belongs to both atoms
