No because Noble gases usually have their valence electrons filled and don't need to make any further bonds

Kehlin Hayes 4C

In a Conjugate Acid, the base gains hydrogens. and the Conjugated Base, the acid loses the hydrogen

Kehlin Hayes 4C

Ligands donate electron pairs

Kehlin Hayes 4C

Organic bases are usually found in organic compounds and can donate electron pairs. Inorganic bases doesn't and disassociates.

Kehlin Hayes 4C

This molecule is tetrahedral because it has four regions of electron density, one being a lone pair.

Kehlin Hayes 4C

yes you are correct

Kehlin Hayes 4C

Just like when writing chemical formulas the subscript of 1 isnt neccessary

Kehlin Hayes 4C

A ligand refers to the molecule that is attached to a central metal

Kehlin Hayes 4C

A bent shape can have either one or two lone pairs

Kehlin Hayes 4C

The oxidation number refers to the overall charge the molecule has

Kehlin Hayes 4C

Order is not important, just know a triple bond means a sigma bond with two pi bonds

Kehlin Hayes 4C

Cis refers to when the atom has the dipole movements on the same side of the molecule making it polar. Trans means the dipole movements are on opposing sides cancelling out making the molecule non polar.

Kehlin Hayes 4C

Yes a triple bond equals a sigma bond with two pi bonds

Kehlin Hayes 4C

The formula would be AX3 because there is one central atom of N and three surrounding O with no lone pairs

Kehlin Hayes 4C

It does not matter, it is best to calculate the formal charge of each atom to see if you have the desired overall formal charge of the molecule.

Kehlin Hayes 4C

You are correct

Kehlin Hayes 4C

Yes but they are slightly different than counting bond pairs

Kehlin Hayes 4C

Yes it is the area that electrons are most likely found

Kehlin Hayes 4C

VSPER stands for Valence Shell electron pair Repulsion and it is not necessary to memorize

Kehlin Hayes 4C

Cis means that the dipole moments of that molecule are on the same side which makes it polar, enabling it to form interactions with other polar molecules. Trans means the dipole moments are on opposing sides of the molecule cancelling out making the molecule nonpolar, this would prevent the molecule...

Kehlin Hayes 4C

It's possible that the dipole forces cancel out and thats why the molecule is nonpolar.

Kehlin Hayes 4C

Yes all molecules experience Van der Waals forces and it has the lowest interaction, although it has the potential to have the strongest interactions

Kehlin Hayes 4C

The stronger the bond the more energy required to break it. So stronger intramolecular bonds would increase melting/boiling points in most cases.

Kehlin Hayes 4C

The bigger the atom the more polarizable it is

Kehlin Hayes 4C

A polar molecule has a partial charge associated with them because of the unequal sharing of electron that results in the molecule having an either positive or negative overall charge.

Kehlin Hayes 4C

Calculating the Formal Charge is a great way to check if the molecule has the correct structure and the correct charge its supposed to have as well as taking the average of all these different structures get us the resonance which the formal charge is calculated for all the structures.

Kehlin Hayes 4C

Yes because the electrons are more stable in that state so the trend still applies

Kehlin Hayes 4C

Usually if electronegativity values are needed they would be provided because the periodic table doesn't show the numeric values of electronegativity, it is important to know how the trend works which is from bottom to top and left to right.

Kehlin Hayes 4C

Right it goes by which atom has the lowest electronegativity which defines how well at atom takes and accepts an electron and the trend goes from top to bottom and left to right.

Kehlin Hayes 4C

After you find the molecular compound its best to see what kind of energy level or bond length there is and what kind of pattern it follows, whether it dissociates it water or not

Kehlin Hayes 4C

Cations are atoms that have lost an electron and therefore receive a negative charge and Anions have gained an electron receive a negative charge. With this being said a Cation is always smaller than their corresponding atom because they are losing a valence electron and Anions are always bigger tha...

Kehlin Hayes 4C

It is still considered a Lewis Dot diagram approach for the electron configuration but Phosphorus is a special case

Kehlin Hayes 4C

Yes material up to and including chemical bonds and resonance

Kehlin Hayes 4C

Drawing them is beneficial in keeping track of the electron figuration and when dealing with finding resonance structures because then the number of valence electrons can vary.

Kehlin Hayes 4C

We don't have to find any bond lengths, they are usually provided in Angstroms that can also specify whether it is a single bond or a double bond.

Kehlin Hayes 4C

l is the second number that gives you the Angular Momentum which determines the shape of the nodes of orbitals.

Kehlin Hayes 4C

It is difficult to find the exact position of particles, particularly electrons, so it measures the uncertainty of that particles momentum and position.

Kehlin Hayes 4C

Which Quantum numbers tell you whether the wave function is in the x, y , or z state? for example 2Px, 2Py, 2Pz?

Kehlin Hayes 4C

Is Heisenberg's Indeterminacy equation only used when trying to find the position and momentum of an electron?

Kehlin Hayes 4C

What is the concept of Hamiltonian Wave Function and how does that relate to the electron Wave Function?

Kehlin Hayes 4C

A photon is the particle of light that is quantized

Kehlin Hayes 4C

The energy levels are discrete, so when the atoms excite and travel through the levels signified by whole numbers.

Kehlin Hayes 4C

For calculations you may use as many decimal places as you see fit to be accurate but its good to use your answer in the least number of sig figs in the question.

Kehlin Hayes 4C

Yes we consider the speed of light in a vacuum to be a constant that we consider c

Kehlin Hayes 4C

The subshell of (c) 4g cannot exist in an atom, I believe.

Kehlin Hayes 4C

Plugging in Planck's constant is in reference to measuring how much energy is exerted by photons.

Kehlin Hayes 4C

Accuracy is defined as how close to the exact amount your measurement was, in other words, how close and correct you were. And Precision is defined as the consistency and closeness of your measurements. Its important to have both when conducting experiments.

Kehlin Hayes 4C

It might also help to examine the full equation and start with the elemnts or molecules taht appear the least amount of times on each side and work your way up.

Kehlin Hayes 4C

The best measure of how many sig figs to use is to look in the question provided and use the smallest amount, it also helps to try and keep the number of sig figs consistent for all measurements.

Kehlin Hayes 4C

You can use the inverse relationship between frequency and wavelength in order to find the constant speed of light.
