Get Hertz with this formula. Z = 3 for Li.
Hertz = (3.29 X 1015 s -1)*Z2*(1/Nf2 - 1/Ni2)
We will reverse initial and final to avoid negatives.
Hertz = (3.29 X 1015 s -1)(32)(1/12 - 1/42)
Hertz = (9.87 X 1015)(15/16)
= 9.25 X 1015 Hertz
------------------------------Now, this formula.
Wavelength = speed of light/Hertz
Wavelength = 2.998 X 108 m/s/9.25 X 1015 Hertz
= 3.24 X 10 -8 meters (109/1 meter)
= 32.4 nanometers

Non-acnegenic means it does not cause or promote acne. Non-comedogenic means it does not cause or promote comedones (blackheads).
promote
A 2 for 1 promote in an exploation carry simply means that to acquire one part working interest you have to pay to the value of two parts.
Not really. We could argue that atoms, at one time or another, absorb a little bit of light of any wavelength, but the most likely scenario is that the atom absorbs light that is of the same amount of energy as the place the atom would use it- in the promotion of an electron. However much energy is required to promote an electron up another level corresponds to the wavelength of light absorbed. Einstein won his Nobel Prize answering a question similar to this where atoms absorb light of a particular wavelength, then release an electron afterward to make electricity. This is known as the "Photoelectric Effect" and we all benefit from it when we use solar cells. Another way to think of the way light is selectively absorbed is to imagine a radio. A radio antenna is exposed to a bunch of signals, but only the station we tune to ends up coming from the speakers. By having electrons arranged in a particular way, an atom acts like a radio receiver- it only receives the signal it is tuned to. Hope that helps and best of luck in your studies! Bill
It isn't. The usual way fluorescence works is indeed that a high energy light promotes an electron to a high energy state and it then cascades down through the energy levels giving off low energy quanta of light at each step. However there is the situation where low energy light input can act as an energy pump and promote an electron in a series of energy steps to a high energy state which it then releases in a single high energy drop emitting a quantum of light of a higher energy than the input.
The outer electron shell of the xenon atom is full, there are no valence electrons to promote activity.
It is NOT negative (for the first IE). Because Be's configuration is 1s2 2s2, we observe that it has no vacant orbital to accommodate an electron, meaning that to insert an electron, it has to go into a new sub-orbital, the higher-energy 2p. Hence, you need energy to promote this electron to a 2p level to force Be to accept it.

Green light does not promote photosynthesis because it is reflected off of a plants leaves. While most plants absorb all other wavelengths of electromagnetic rays from the sun, they reflect the wavelength for green light.
orientation of incoming Nitro group is destined by already present group on benzene ring . if already present group is electron donating group, it will promote electron density at ortho and para position and , therefore, nitro group is formed on ortho and para position.
Yes, promote does have a prefix. Promote's prefix is pro-.
