The cisplatin has the two chlorine atoms on the same side of the molecule, therefore, both chlorines are replaced by nitrogens in adjacent guanine base pairs. This stops the replication mechanisms from replicating the DNA because the cisplatin has stopped it.

I do not think that we will be given the electronegativity of the atoms if asked if THERE IS a dipole moment because you can tell if there is a dipole by the periodic tends. Whoever, if we were told to CALCULATE the dipole moment, then we probably would be given the electronegativities of the atoms.

It is not the interaction between ions and dipoles that determine the phase, but the size of the atom/molecule. For example, fluorine gas, F 2 , is a gas at room temperature, while diiodine, I 2 , is a solid at room temperature. F 2 has 9 electrons while I 2 has 53 electrons. This means that the ins...

Polarizability is the ability for a molecule to form dipoles. This has to due with the number of electrons in the molecule and the size of the molecule. The larger the molecule, the lower the effective nuclear charge is on the outer electrons. This means that it is easier to distort the outer electr...

A dipole occurs when you have a polar molecule that has two opposite charges. For example H 2 O has a dipole because there are polar bonds between the hydrogen and oxygen, making oxygen slightly positive and hydrogen slightly negative. An induced dipole can occur in any molecule (polar or nonpolar) ...

You can determine if a molecule is polar or nonpolar from the Lewis Structure. If the molecule has no polar bond than it will be nonpolar. Also, if the molecure has polar bonds, but the dipole moments are equal and in opposite directions, then the molecule is nonpolar. If the molecule is has polar b...

The atom in the middle (central atom) usually has the lower ionization energy than the atoms on the outside (terminal atoms) because they share their electrons more readily than atoms with higher ionization energy, resulting in a structure with the lowest energy.

Six electrons in a given electron can have the quantum numbers n=5, l=1.
n=5, l=1, m_l=-1, m_s=+1/2
n=5, l=1, m_l=-1, m_s=-1/2
n=5, l=1, m_l=0, m_s=+1/2
n=5, l=1, m_l=0, m_s=-1/2
n=5, l=1, m_l=1, m_s=+1/2
n=5, l=1, m_l=1, m_s=-1/2

There is not a maximum amount of electrons that can be gained or lost by an atom, however, it would not be favorable to add 6 electrons to a Beryllium atom to get the octet. It would be easier for the atom to lose 2 electron to get this octet. For Oxygen, it would be the opposite. It is not favorabl...

No because the charge of the nucleus does not change when you form an anion so the electrons are not pulled closer to the nucleus.

The energy difference occurs because when you ionize the Group 2 elements you are taking an electron from a full subshell (s^2) whereas when you ionize the Group 13 elements you are taking an electron from a subshell of higher energy, but with only one electron in it (p^1). The full s subshell is mu...

The units that you end with depend on what value you are solving for. If you are trying to find ∆x, it would be meters. If you are looking for ∆p, it would kg•m/s.

This unit is actually used for frequency, not wavelength, and the units will cancel out with each other to give you s^-1, or hertz (Hz). The units for wavelength will be either m or nm.

Principle quantum levels are similar to the electron orbitals and suborbitals. The energy levels are described by quantum mechanics, hence the name quantum levels. This means that each level has a certain minimum energy required for the electron and if the energy of the electron is between two level...

He said that for the class we will say that 10^-18 is detectable, but on tests we will have obvious answers when asked whether a wave is detectable, such as 10^-8 of 10^24.

The equation M1V1=M2V2 is used when you are given the volume and molarity of one solution and are told to use that solution for find molarity of a solution with a known volume or volume of a solution with a know molarity. The equation molarity=moles/volume is used when you have two of the variables ...

When frequency doubles, this means that there are more oscillations per second. For this to happen, the wavelengths have to be shorter, in this case they would be halfed. Basically the frequency and the wavelength have an inverse reationship, if one increases, the other has to decrease.

Maharsh Patel 4E

The equation is actually C=Lambda x V and it does not involve the energy of the wave, but shows that when you multiply frequency and wavelength, it equals a constant.
