1)Electrons in the 2s and 2p orbitals have _______________ quantum numbers n and electrons in the 2s and 3s orbitals have _____________ quantum numbers n.2) A molecule of oxygen gas (O2?) has a velocity of 2800 m?/?s.What is its de Broglie wavelength?3) What is the electron configuration of the oxide ion (O2-?)?4) A string that is restricted at both ends has a length of 1.50 m. What is the wavelength of the string’s fundamental frequency?Here are the last four things i want to check. Please help in desperate need of a good grade on this
