When doing VSEPR formula, X are atoms whilst each E is a lone pair on the central atom.

ElliotPourdavoud 1A

A radical is an atom or molecule with an unpaired valence electron, or molecules with an odd number of valence electrons.

Commenting so I can come back to this when studying ligands.

ElliotPourdavoud 1A

The acid is the one that picks up the Hydrogen proton, while the base is the one that loses the hydrogen proton.

ElliotPourdavoud 1A

I have this same question...I'm gonna comment so I can come back to it later.

ElliotPourdavoud 1A

I don't trust atoms.... I heard they make up everything.

ElliotPourdavoud 1A

The metals lose electrons very easily so their charge is always positive.

ElliotPourdavoud 1A

Thank you very much for this!

ElliotPourdavoud 1A

I don't think this is the case, a Lewis acid is an acid that can accept an electron whilst bronsted acids are proton donors.

Professor Lavelle said in class for ones that are slightly less than the norm, you have to just search it up, I think saying that it is less than 109.5 is fine for the homework.

ElliotPourdavoud 1A

There's the normal ones like tetrahedral that you can just memorize, but for a lot of molecules where those angles are tweaked a bit you can't just memorize them other than knowing that they will be greater or less than the usual value.

Since water is polar, it has both negative and positive regions in the molecule, the reason this is good for dissolving ionic compounds is that the water molecule and the ionic compound attract each other and thus it dissolves in water, while nonpolar molecules repel away from water and don't dissol...

Another way is to count each electron that surrounds the atom in question and give it a value of 1 (ex. if an atom has 1 lone pair, you count both electrons as 1) then you count each bond as 1, (ex. if an atom has 2 bonds each bond is counted as 1) then you just add those values together and subtrac...

I think it's because the electrons are still within that region, instead of it having one pair that is located there, it is two or three pairs there but they are still in that region.

ElliotPourdavoud 1A

I believe that formal charge is a good way to see if an atom can have an expanded octet to make it the most stable.

ElliotPourdavoud 1A

Yup, all molecules have london forces I believe due to the way electrons orbit the atom.

ElliotPourdavoud 1A

The human body is primarily composed of Carbon, Hydrogen, and Oxygen, and a little bit of Sodium, so that means we're 100% NaCHO ;)

ElliotPourdavoud 1A

From my understanding, it must have an octet or an expanded octet but not less.

ElliotPourdavoud 1A

Tagging on with the other posters formal charge is the explanation for the answer.

The schedule says they begin Tuesday November 27th.

I did the problems towards the end of chapter 3.

ElliotPourdavoud 1A

Thank you so much for this review it really helped me!

What show do Cesium and Iodine love watching with one another?

CSI

ElliotPourdavoud 1A

If I'm not mistaken both methods are correct, it depends on what you feel more comfortable with.

ElliotPourdavoud 1A

It signifies the charge of that atom as some elements have different ion forms.

ElliotPourdavoud 1A

Non metals tend to gain an electron simply due to their valence electrons needing a small number of electrons to complete their octet rather than losing those electrons.

ElliotPourdavoud 1A

As the person above me stated, atoms with higher ionization energy are less likely to lose an electron to become a cation.

ElliotPourdavoud 1A

What is a cation afraid of? A Dogion!

ElliotPourdavoud 1A

It should be given as a constant.

ElliotPourdavoud 1A

I'd just go with what the outline for test 2 had on Professor Lavelle's website.

ElliotPourdavoud 1A

Did you hear oxygen went on a date with potassium?

.....it went OK.

ElliotPourdavoud 1A

As someone said before, I do most of my homework in pen and it does take some getting used to but it has allowed me to be comfortable using a pen on exams in my previous courses.

ElliotPourdavoud 1A

Avogadro's constant will apply to molecules as well as individual elements it is a mol of the molecule or a mol of the atom.

ElliotPourdavoud 1A

I think Professor Lavelle just said any post counts as a post and you have to do 3 per week.

ElliotPourdavoud 1A

No, I'm pretty sure that the states of matter don't affect balancing as the only thing that does is the quantity of atoms.

ElliotPourdavoud 1A

Atoms per mole is a constant, so if they have the same amount of atoms they have the same amount of moles.
