Answer to Question #243339 in General Chemistry for Prezoul

Question

A proton of 498nm was emitted from a silicon atom. Calculate the energy of all the atomic levels of silicon and show that the atomic levels are quantized

Answer 1

$E=\frac{hc}{λ}$

where:

• $h=6.626 × 10^{−34}$ J is Planck's constant
•  $c=3×10^8m/s$ is the speed of light

$E=\frac{6.626×10^{-34}×3×10^8}{498}= 3.99×10^{-28}$
