Naming Compounds
What is the chemical formula of Iron (III) Oxide?

What molecular geometry is formed when you have 3 bonds and one lone pair?
trigonal pyramidal
What is the general trend across the periodic table?
Increasing from bottom left to top right
What is a balanced reaction?
One in which the amount of things on the right side equals the number of things on the left side.
What is the name of NaHCO3?
What is the name of the largest molecular geometry?
octahedral
What are the three most electronegative elements on the periodic table?
FON
Is this balanced?

No
When naming compounds, what is the instance where you have to introduce a pre-fix in front of the element names?
When you have only non-metals binding.
What is the molecular geometry of ClF3?
t-shaped
What does it mean to be electronegative?
Electron attraction
Why must we balance reactions?
Because we cannot create or destroy atoms during a chemical reaction, thus they must always be present in some capacity at the end of the reaction.
