Re: Hydrogen bonding

Hydrogen bonding is between molecules, whereas covalent bonding is between atoms.

Re: Chemical Formulas

Also on the Sapling questions we were expected to know the formulas for nitrite and phosphite. We didn't really go over naming ions in class so I was wondering if we also had to know formulas for all ions?

Re: Energy

I believe it is referring to the energy of the electron. When the electrons are farther from the nucleus (higher energy level), they have a higher energy.

Re: ground state electron configuration

A ground state electron configuration is when the electrons are at their most stable. For the electron configuration of a ground state electron, the orbitals are filled in order. In an excited state electron configuration, electrons can jump to a higher energy level. This means the electron configur...

Re: textbook F13

Chlorine is only diatomic (Cl2) when it is standing alone, like O2. So for the molar mass, you would just use 35.5.

Midterm topics and information

I tend to retain more information and learn better by studying the textbook. Will all the information needed for the midterm be in the textbook chapters? Will there be lecture-specific questions on the midterm that I can't learn in the textbook?

Re: Sapling Week 2/3 question 4

@Lindsey Su You would have E, the energy per photon from the previous part, so dividing the total energy 3.08x10^-7, by the energy per photon should give you the number of photons. If each photon only ejects one electron, then this should be equal to the number of electrons that were ejected. Thank...

For the second part of the question, it asks you to find the maximum number of electrons that could be ejected from the metal by a burst of photons with a total energy of 3.08x10^-7 J. Do I need to use the work function I calculated in the previous question? How would I solve for the number of elect...
