This is kind of funny but to remember acids bronsted vs. lewis I use, my Bro(nsted) is a Pro(ton) with Do(nor), and then I just remember that the Lewis acid involves electrons and accepts them so A(cid) (A)ccepts.

To follow up, is it alphabetical order by prefix or by the names of the ligands?

It is alphabetical order by the name of the element, so monochloro would come before dioxide. Hope that helps.

Ligands are just molecules bonded to the central atom that help make up regions of electron density. Ligands always follow the octet rule, except hydrogen which can have 2 electrons in its valence shell. Hope that helps.

Covalent character just means that instead of one element fully stealing electrons from the other their electron clouds share, not to the extent that covalent bonds share electrons but there is some sharing rather than solely taking electrons. The larger the atomic radii of an element the more easil...

The terms "bent" and "angular" are interchangeable and mean the exact same thing so you will be given full credit no matter which term you use as long as that is the appropriate shape.

katietietsworth_3c

There is no chart, but it helped me to make my own chart with bond angles, shapes, electron domains, hybridization and polarity and memorize that for the test. Good luck!

katietietsworth_3c

when there are a double or triple bond hows does that affect the vsepr structure?

katietietsworth_3c

I am confused how to do hybridization within problems does anybody have a good way of explaining how to solve these problems?

katietietsworth_3c

Does anyone have a trick to figuring out the vsepr shape from the lewis structure?

katietietsworth_3c

F only has 7 valence electrons so for it to be able to stabilize and form an octet which is what the molecule ultimately needs to achieve stability it needs to covalently bond with H, sharing the pair formed between them which is why it cannot form a double or triple bond, the rationale for Fluorine...

katietietsworth_3c

can someone explain to me the difference between sigma and pi bonds I was a little confused on their meaning in lecture.

katietietsworth_3c

I am having trouble distinguishing between tetrahedral and trigonal planar, how can I know which the Lewis structure is?

katietietsworth_3c

The actual structure would be 3D since molecules exist in a 3-dimensional world. All Lewis Structures are 2D forms of molecules which is why they can have multiple different structures but the VSPR models display how molecules look and function according to the laws of the physical world.

How can you determine which compounds have higher boiling points vs. which have lower ones?

katietietsworth_3c

I am confused about the meaning of an induced dipole, would someone mind explaining what the two terms mean in relation to each other?

katietietsworth_3c

When doing an example like BF3 how will we be able to know that all of the F elements have an octet but B only has 6 electrons? Would this be something we might see on a test? I am just confused on how we can know which element to put the octets on when it comes to a compound like BF3 that has 24 el...

How do we know if an element can be negative or positive if it is impossible to make them both charged to 0?

katietietsworth_3c

Hi, I am confused on how to figure out how many valence electrons each element has. How can I determine this?

katietietsworth_3c

How can you distinguish if an element has a full octet? Does each orbital have to have a full octet before moving to the next orbital?

katietietsworth_3c

How do we know which electrons are the outermost electrons? And how do we count them?

katietietsworth_3c

Hi, I was wondering why the 3d and 4s orbitals are on the same row of the periodic table. That whole thing is confusing to me does anyone know why that happens?

katietietsworth_3c

Does anyone know which equations are going to be on the equation sheet for the test this section?

katietietsworth_3c

I don't understand what the Lyman, Balmer and Pascal principles mean in context, can someone explain.

katietietsworth_3c

Does anyone have a way to remember SI units and which units go with which variable in equations to make it easier to do stoichiometry? Please let me know.

katietietsworth_3c

Hi I am confused on how to calculate the energy gained or lost when an electron moves up an energy level/dropped. Can someone please explain the steps to calculating the change in energy.

katietietsworth_3c

When solving if a certain object has wavelike properties I'm confused why numbers with less than 10^-18 do not show wavelength properties. Can someone explain what this threshold means and what the boundaries of a wavelike property are.

katietietsworth_3c

Hi all, I was wondering if anyone knew of any additional online resources to learn the concept of this section since I have been a bit confused on it. Let me know if you know of any websites of youtube videos. Thank you.

Hi, I have trouble doing dilution problems and figuring out which volume is V1 vs. V2. Also I have issues on where to start with a lot of questions, i read them then I get confused on what I'm supposed to be doing, any tips on how to combat that?

katietietsworth_3c

I am also confused as to whether or not to get a solutions manual and does it have step by step help or just one answer? Do they still have them at the student store or can we find them online? I definitely want to check my answers and I just rented the hardcover textbook but wasn't told we needed a...

Hi all, I have never been great at being able to balance equations just by looking at them, does anyone have any tips on shortcuts/methods they use to help them balance equations especially when they get complicated? Also if you know of any youtube chemistry help that would be appreciated, I am a ve...

katietietsworth_3c

Hi, after dividing by the smallest value how would you know what number to multiply by if more than one of the numbers isn't a whole integer. For example, in the vitamin C example you end up with 1.00C:1.33H:1.00O then multiply them by three to get whole integers but what would you do if you had for...
