This was very helpful thank you

what are the bond angles for pentagona bipyramidal

Leslie Contreras 1D

Leslie Contreras 1D

what makes a vsper shape polar or non polar?

Leslie Contreras 1D

Are we suppost to memorize the hybridization of each shape or how do I figure it out?

Leslie Contreras 1D

I am not too sure their significance in hybridization orbitals

Leslie Contreras 1D

is the product of a Lewis acid-base reaction in which neutral molecules or anions (called ligands) bond to a central metal atom (or ion)

Leslie Contreras 1D

how do lone pairs affect bond angles?

Leslie Contreras 1D

You just said in class "These are found experimentally. You will not have to memorize"

Leslie Contreras 1D

What determines the angle of the bonds in a molecule?

Leslie Contreras 1D

I was under the impression octet expansions fall under the d orbitals but during an HW problem, Cl was able to expand its octet. I guess my question is what constitutes the octet expansion?

Leslie Contreras 1D

I get these scrambled is it that they have a small radius that they have more ionic character or less?

Leslie Contreras 1D

There is an example in the book about identifying the greater lattice energy?
it said the ionic radius of NaCl is less but what does that have to do with lattice energy?

Leslie Contreras 1D

Why are multiple bonds shorter than the single bonds?

Leslie Contreras 1D

Why does the bond weaken in the change from a triple bond in N2 to single bond in F2?

Leslie Contreras 1D

Why does the electron cloud of the anion get distorted?

Leslie Contreras 1D

I saw the back cover for the constant but I'm still not sure why there is an importance to it
they describe epsilon zero
z1 and z2 and e
but not permittivity

Leslie Contreras 1D

Thank you that really helped
both of you

Susu Le 1F wrote:That energy is required to overcome the effective nuclear charge that is acting on the electron.

SORRY I still do not understand

Leslie Contreras 1D

when you add the electron to Calcium the energy required is 494
where is that number found?
what constitutes as required a cation needing to push an electron or is that released because of the electron leaves?

Leslie Contreras 1D

In the book, ionic bonds are the transfer of electrons then it says covalent bonds share electrons.
Why do they have such a big difference don't they share either way?

Leslie Contreras 1D

I keep re reading "due to electron repulsion electrons in the same subshell occupy different orbitals with parallel spins (lowest energy)"
But I do not entirely know what it means

Leslie Contreras 1D

why can hydrogen spin either -1/2 or +1/2

Leslie Contreras 1D

in the book, n is the quantum number, related to size and energy
How does it relate to orbitals?

Leslie Contreras 1D

so we stick to ch.1 and chapter2

Leslie Contreras 1D

For this weeks homework do we do chapter 3 set of problems

Leslie Contreras 1D

Is Atomic number Z a constant used to be able to see other elements besides Hydrogen atoms

Leslie Contreras 1D

Which one is the SE equation V(r)= or En=
The book gives those but I am not sure how they are related?

Leslie Contreras 1D

I don't get the very first sentence, " An electron in an atom is like a particle in a box, in the sense that it is confined within the atom by the pull of the nucleus "
How are e- confined?

Leslie Contreras 1D

Do we have to memorize the spectrum if not how do we calculate its energy in order?

Leslie Contreras 1D

in this example, I am unclear what exactly the formula is to be used in these situations? What exactly are we trying to find?

Leslie Contreras 1D

In using the uncertainty principle in the textbook why did they replace h as 1.05457x10^-34
in example 1.7

Leslie Contreras 1D

We were only shown Weins law but will we use Stefan-Boltzmann
law Total intensity=constant xT^4
When will this concept come up? Can someone explain to me why T^4

Leslie Contreras 1D

Why is it that after finding the frequency we divide it by plancks constant to then put it in the speed of light equation (wavelength= speed of light/frequency.

Leslie Contreras 1D

The Molar mass is 84g.mol and its empirical Formula is CH2. What is its Molecular Formula?
I'm not sure how to start but I understand the process?
