Question

Quantum mechanics is based on the idea that: O Matter can have wave-like proeprties OAn atom has an infinite number of energy levels OMatter and energy are interchangeable O Light can have matter-like properties QUESTION S 5 points How many electrons are required to fill all the orbitals for which n-2? O8 10 5 points Sa QUESTION 6 Which of the following states Hund's rule? OWhenever orbitals of equal energy are available, electrons arrange themsel obtain the maximum.number of unpaired spins OElectrons are always placed first into the lowest-energy orbitals available Electrons must always be placed into the orbitals in pairs O An orbital can hold no more than two electrons 5 points. QUESTION 7 Which element has seven valence electrons? O Carbon O Nitroger O Oxygen O Fluorine 5 points QUESTION
