Problem- 1) Determine the identity of the following excited element. Explain 1s^22s^22p^23d^1
2) Write the ground state electron configuration and the corresponding orbital diagram.
3) Calculate the wavelength of the light that is produced when the excited electron relaxes the back to ground state.
4) In what region of the electromagnetic spectrum does this wavelength fall?
I am thankful to receive an expert help to solve the above problem
Scientists can use mutants to study metabolic pathways. These organisms have a mutation in a gene encoding a metabolic pathway enzyme that results in the inactivation of that enzyme
