- 7. Multiple ChoiceHow many orbitals do p orbital have35610
- 8. Multiple ChoiceHow many orbitals do d orbital have35610
- 9. Multiple ChoiceHow many electrons do d orbital have?35610
- 10. Multiple ChoiceWhat relationship does wavelength have with frequency and energy?A proportional relationship. As wavelength increases so does frequency and so does energyAn inverse relationship. As wavelength decreases, frequency increases and so does energyA proportional relationship. As wavelength increases so does frequency and energy decreasesAn inverse relationship. As wavelength decreases, frequency increases and energy decreases
