So I have an exam coming up and I'm working on the review and I was wondering if you guys could answer a few things.
1) What is the relationship between atoms and ions.
2) What is the relationship between elements in families of the periodic table.
3) What is the relationship between slope and speed.
4) What is the relationship between populations and communities.
5) Compare families and periods on the periodic table.
6) How do you determine the number of atoms in compounds.
7) How do you determine the rate of acceleration.
8) How do you determine the acidity from a pH scale.
Any help would be appreciated.
