in this molecule, Xe has six regions of electron density. It has two lone pairs and four bonds with F, so it would be a sp3d2 hybrid orbital

JulietOttenberg-1C

there are multiple configurations that qualify as "bent"

JulietOttenberg-1C

HI has a larger atomic radius so it is dissociates easier than HCl

JulietOttenberg-1C

the most important thing to remember about them is that they do not dissociate completely in water, as opposed to strong acids

depending on where they are positioned, they could decrease the bond angles of the atom. If there are multiple lone pairs, they usually repel each other even more than bonding pairs so it really just depends on the structure.

JulietOttenberg-1C

Because pi bonds consist of electron density on either side of the internuclear axis, the atoms cant really move out of that configuration or else the bonds wouldn't be there. It's basically just because pi bonds have two areas of electron density rather than one area.

JulietOttenberg-1C

I think this is because the lone pair repels the bonds that are closer to it more than the other bonds. Also, the bonds themselves repel eachother, so this shape is what occurs when all this repulsion balances out.

JulietOttenberg-1C

no I don't think it matters.

when one molecule has a dipole, it means that there is a partial positive charge on one atom, and a partial negative charge on some other atom of the molecule. these partial charges attract or repel the electrons of nearby molecules' bonds. So, if there is a polar molecule with a dipole, the partial...

JulietOttenberg-1C

When the molecule has a charge, all the formal charges of the atoms in the molecule added together will add up to the charge of the molecule

JulietOttenberg-1C

cations tend to be smaller in size because the positive charge of the atom is stronger than the negative charge of the atom. There is also less electron shielding, so the outer electrons are pulled in tighter by the positive nucleus.

I'm pretty sure a line represents two shared electrons in a covalent bond.

JulietOttenberg-1C

Yes that is correct because all the rules are being followed

JulietOttenberg-1C

No it doesn't. Electron configurations describe atoms and their specific electron structure, while polarity is much more relevant with molecules their shapes and lewis diagrams.

JulietOttenberg-1C

I don't think it matters too much, but only as long as all the other laws are followed

JulietOttenberg-1C

7, so a filled f orbital would have 14 total electrons

JulietOttenberg-1C

Excluding exceptions, the sublevels are filled from lowest to highest energy. The 3d sublevel gets filled before any of the sublevels after it (such as 4p and 5s and 4d) because it has a lower energy

JulietOttenberg-1C

Because electrons move so fast, we can never calculate exactly where one is at a certain moment in time. Because of this, we have created the idea that orbitals are areas where we are most likely to find electrons. So, electrons of a certain energy are likely to be found in the orbital that correspo...

Quanta refers to distinct packets of energy. Light has to reach a certain threshold energy to change energy levels, or, in other words, light isn't continuously changing.

JulietOttenberg-1C

This refers to how there can be two electrons in an orbital but they are not moving in the same direction. There can be six electrons in the 2P energy level, but in every electron pair, they are drawn going in the opposite directions (one of the arrows points up and the other points down)

JulietOttenberg-1C

yes velocity is (planck's constant)/(wavelength)(mass). I'm fairly certain the main difference between velocity and speed is direction, and I think the only possible thing that could change in your answer is the positive or negative sign. Maybe check the numbers and there might be a miscalculation

JulietOttenberg-1C

I usually balance the atoms that are solo last because it makes it a little simpler. For example, in combustion reactions, it's usually easiest to balance every other atom before the oxygen molecules because they're alone so you don't have to keep changing all the numbers.

JulietOttenberg-1C

For our test it didn't matter how they were connected, and I don't think this ever really matters for empirical formulas. You had to count the amount of each atom in the structure to find the molecular formula. To find the empirical formula, you use the smallest version of that same ratio of atoms. ...

A change in the magnetic field implies a change electromagnetic radiation. When the frequency decreases, there are less waves in an amount of time, or the waves become less "frequent". They are moving slower, and therefore less waves of radiation will interact with the magnetic field and c...
