Re: Bronsted vs Lewis

In what scenarios do elements use their bronsted definition and when do they use their lewis definition? In other words, are there certain types of reactions that use one of the definitions more often?

Re: pH and pOH

Why is it more common to measure the pH of something rather than the pOH?

Re: Energy of Hybrid Orbitals

Going along with energy of hybrid orbitals, how do they compare to other non hybrid orbitals and why do they occur?

Re: Angular VS Bent

I agree with the previous responses that they are basically the same thing. Usually when one says angular they will be talking about the bond angle between two atoms and give a specific measurement, while bent is more of just a general statement.

Re: Trigonal planar vs. Trigonal bipyramidal

Trigonal planar is when there is a central atom and 3 bonding pairs, trigonal bipyramidal is when there is a central atom and 5 bonding pairs.

Re: atomic size

The atomic radius of an element in the upper left would be smaller than the atomic radius of an element in the bottom right because its energy level would be very low and thus the electrons would be held very closely to the nucleus compared to the element that has high energy levels.

Re: Ionization Energy [ENDORSED]

Usually when you go across the periodic table the ionization energy will increase but when going from N to O this is not the case. This is because when adding another electron into the px orbital the electrons repel against each other due to their similar charges which causes the ionization energy t...

Re: EM spectrum

It is not required to know the exact wavelengths of the spectra but I do think it is important you know the general idea of what order the waves go in. For example you should know that infrared wavelengths are longer than visible light wavelengths and that visible light wavelengths are longer than u...

Re: Energy Level Change

I believe it is possible for electrons to drop down to levels other than n=1. If the change in E is not equal to the amount necessary to move it back down to n=1 then it cannot go there. However, n=1 is the most stable state so the electrons are going to want to move down to that level.

Re: Molecules [ENDORSED]

A mole is a unit of measure that defines the amount of a chemical substance that contains as many "things", such as molecules or atoms, as there is in 12 grams of carbon-12. The a molecule is one of those "things" that can make up a chemical substance and is the smallest fundamen...

Re: Percent Yield [ENDORSED]

Having a high percentage yield is good because that means the product is being created to its full capacity. This is important when performing experiments because chemists want to make sure they are being as accurate as possible and if not all their product is forming then this can cause for wrong m...
