Given that the wavelength of maximum absorption for chromium is 574.7 nm, what is the energy per cr atom of the transition for an electron to move from one d orbital to another of higher energy? (h = 6.626 x 10-34 js/particle, c = 3x108 m/s)

Explanation:

Where,  

h is Plank's constant having value

c is the speed of light having value

is the wavelength of the light

Given,

Thus, applying values as:

i have no clue hope you find the answer

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
