Using hydrogen in his experiments Bohr showed that an electron spins around the atom nuclei at a specific/discrete radii (orbital levels). Electrons at every orbital level spin at a discrete angular momentum and energy. When the electron moves one orbital level down, it releases a photon of energy specific to the jump (that is, of a particular spectrum that is unique to the atom). When the electron goes up an orbital level, energy (of a specific spectrum) is absorbed. This emission and absorption spectrum varies across atoms and is calculated as (delta)E = hf where;
E = energy
h = Planck's constant
f = frequency
The element named after Thor, the Scandinavian god of war?
Thorium
If there is electrochemical cell where Q = 0.0010 and K = 0.10 then the truth about Ecell and E°cell is,
Ecell is positive and E°cell is negative.
E° = (RT/nF) InQ = (RT/nF) × In(K/Q) = Positive.
Since ( K/Q) = 100 then In(K/Q) = positive
Which one all of the or what
