when the orbitals aren't listed in the "s-p-d-f" order, which is preferred?

angelagd3l

Should we be able to draw similar examples on Test 3?

angelagd3l

it is important to indicate the value before the shell, just to be safe you should double check with your TA

angelagd3l

when (if) this happens how can we differentiate between the two characters?

angelagd3l

when can resonance structures help with drawing other models?

angelagd3l

are there any exceptions to this trait when drawing the structures?

angelagd3l

Do lone pairs also affect the way the model is oriented? Because of the repulsion?

angelagd3l

the more hydrogen bonds the higher melting points?

angelagd3l

is it helpful to use hybridization even if its not asked to?

angelagd3l

why should the sigma bonds be formed before pi bonds?

angelagd3l

Will Test 3 require us to draw 3D models? With Wedges?

angelagd3l

does anyone know a good way to study *conceptually*? I find it confusing sometimes.

angelagd3l

I learned that it's easier to memorize each general one, but if you want to learn a trick then it's better to look at the shapes.

Nitrogen has lower electronegativity which is why it is in the middle

angelagd3l

its easier to know the trend, and if you tried to figure it out differently it would probably be less accurate

angelagd3l

if it can easily lose an electron then there is a lower electron affinity

angelagd3l

i think since chlorine is larger than oxygen (because it has more valence shells than fluorine)

angelagd3l

they can help you with figuring out how to draw the lewis structures or electronic configurations

angelagd3l

i think normally they would provide that but other hw questions may need you to know them.

Midterm covers: Fundamentals, Quantum, Bonding to end of 3.11 (6 Ed.) and to end of 2C (7 Ed), up to Wednesday.

angelagd3l

normally you put the atom with the lowest ionization energy

angelagd3l

Besides drawing the lewis structure is there another way to find a radical?

angelagd3l

What does the 'H' stand for in this equation?

angelagd3l

Can De Broglie's Wave Equation work for any particle with momentum?

angelagd3l

Why do electrons have quantized energy?

angelagd3l

Is it possible to specify the position and momentum of a particle?

angelagd3l

what units are we using while working with wavelengths?

angelagd3l

Does the answer always have to be negative? Since its decreasing?

you use it when you're solving for an energy change

angelagd3l

When we are rounding, how can we determine how many sig figs we need to keep in the problem?

angelagd3l

it mostly always is determined by the problem

you must at least answer/ask three things on the website every week!
