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:

a galvanic cell( aka voltaic cell) and electrolytic cell

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
