Question- (1) An electron in the n = 6 level of the hydrogen atom relaxes to a lower energy level, emitting light of λ = 93.8 nm. Find the principal level to which the electron relaxed.
(2) What is the velocity of an electron that has a de Broglie wavelength approximately the length of a chemical bond? Assume this length to be 2.9×10?10m
Solve the above problem in detail no word count
Given that the sample is a mixture of multiple chemicals and you are NOT given a mixture of KNOWN quantities, what experiement(s) should we do to create our own KNOWN data
