Re: Why can't SO2 form Hydrogen bonds?

is it because there isn't a partially negative charge?

Re: What does ground state mean? [ENDORSED]

It means the lowest energy. Atoms and molecules, if left alone, are in their ground state (lowest energy). Therefore, as I discussed several times in class, we can figure out the electron configuration without needing to memorize them. By extension, how would the electron configuration be for excit...

Re: 3d before 4s

Alma Flores 1D wrote:The 4s orbital has higher energy then the 3d orbital. After the 4s is completely filled, 3d is lower in energy than 4s.


Although I know this to be true, is there an explanation as to why 3d is lower in energy than 4s only after the 4s is completely filled?

If we're finding the electron configuration for, say, an ion with the same amount of electrons, would it also follow the same rule?

Is there a more efficient way to balance out equations? I know the fundamentals of balancing it's just tedious sometimes. What's a trick in doing it faster?
