Re: Cisplatin

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.

Re: Identifying whether there is a dipole moment

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.

Re: phases caused by interactions

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...

Re: Greater polarizability of larger molecules

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...

Re: Dipole vs Induced Dipole

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) ...

Re: Polar vs 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...

Re: Ionization Energy over Electronegativity?

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.

Re: Extra electrons

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...

Re: Atomic Radius

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.

Re: Horizontal Trend (Group 2 and Group 13)

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...

Re: Units

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.

Re: Units for Wavelength

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.

Re: Proving c=Δv

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.

Re: C=Delta x V

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.
