Question

What is the wavelenght of electromagnetic radiation absorbed when a gaseous X atom coverts to X+ ion which the first ionization of X is 903.3kJ/mol.?

Answer 1

`2.2 × 10^-31\ "m"`

Explanation:

Wavelength of an electromagnetic wave is given by

`λ = "hc"/"E"`

`λ = (6.626 × 10^-34\ "J s" xx 3 × 10^8\ "m/s")/(903.3 × 10^3\ "J") = 2.2 × 10^-31\ "m"`
