when not to use the light equation?

When are you not allowed to use the light equations when answering questions? TAs & UAs have made it clear not to use light equations for certain problems, but I never know why/when not to.

Re: Ionic Radii

anions gain an electron, so that can add an n, which makes the radius larger. Cations lose an electron, so that can take away an n, making the radius smaller

What should the order of electron configuration be? It should be 1s,2s,3s,3p,4s,3d I thought? Some people are saying 1s,2s,3s,3p,3d,4s to keep the n's together, though

the textbook can scare me, but it's best to break it down. Don't read too much in one sitting and take notes on things that scare you. If you really don't understand a concept, try looking at videos on Youtube!

Re: How would sig figs be used in a problem?

You just need to make sure the answer you give to the problem has the correct amount of sig figs. So just follow the sig fig rules. Your answer should have the same amount of sig figs as the number in the question with the least amount of sig figs.
