Which two chemicals did you have available as catalysts for the electrolysis lab?
400
Alkali Metals and Halogens, which can be determined by their valence electrons...Alkali metals = 1 and Halogens = 7.
What two families are most reactive and how can this be determined?
400
No, they are simply attracted to one another due to opposite charges.
Are atoms involved in ionic bonding situations truly bonded together?
400
single covalent bond

How many valence electrons create a stable Hydrogen atom?
500
Na loses an electron and Cl gains and electrons and then they are attracted to one another due to opposite charges
