Re: Momentum Uncertainty

because λ = h/p, decreasing the uncertainty of p decreases the uncertainty of λ.

Re: Speed of light

For homework, I have just been using 3.0x10^8 m/s and it is fine, but for the tests my TA said that the answers on their score sheet are calculated using the exact constants that are on the equation sheet.

Re: Polar vs Nonpolar

You determine the polarity of the bonds in a molecule by taking the difference in electronegativity between the two atoms involved. If the difference is less than 0.4 then the bond is nonpolar. If the difference is greater than 0.4 the bond is considered polar. If the molecule has no polar bonds the...

Re: HW 1.33b

because you are looking for the exact energy needed to eject the electron and no more, solve the equation (Energy of photon) - (work function) = (Electron Kinetic Energy) with kinetic energy = 0 so you're essentially solving for when (Energy of Photon) = (work function). Therefore you can solve the ...

Re: Photoelectric Effect

As long as the wavelength of light being emitted from the source is short enough to eject electrons from the surface then increasing the intensity (number of photons) of the light would increase the number of electrons being ejected, because each photon has the potential to dislodge one electron.

Re: Schrodinger and quantum numbers

The solution to Schrodinger's Equation solved in three dimensions is the three quantum numbers n, l, and ml, and they are related to each other by the wave function ψ. ψ represents the state of the electron around an atom, so ψ could be described as a mathematical representation of an orbital. ψ its...

Valence Electrons

Why does a full shell of valence electrons contain 8 electrons? Where does this number come from?

6th ed. problem 2.27

This question asks to identify the number of orbitals associated with each quantum number. The solution manual states that 5d has five orbitals, 1s has one orbital, 6f has seven orbitals, and 2p has three orbitals. How do you determine this?
