Question
The range of characteristic frequencies of electromagnetic radiation that are readily absorbed and emitted by an atom is diffraction Hund's Rule Photoelectric effect Atomic spectrum The quantum number specifies the energy of an electron and the size of the orbital. spin magnetic principal secondary or azimuthal none of the above When a electron in a 2porbital of a lithium atom makes a transition to the 2s orbital, a photon of wavelength 670.8 nm is emitted. The energy difference between these 2p and 2s orbital is 2.96 times 10^-10 J 2.96 times 10^-19 J 3.38 times 10^18 J 2.96 times 10^-17 J none of these Which of the following atoms or ions has 3 unpaired electrons?
