Question

29 explain the aufbau principle. * (0.5 points) electrons occupy equal - energy orbitals so that a maximum number of unpaired electrons results. electrons are added one at a time to the lowest energy orbitals available until all the electrons of the atom have been accounted for. electrons all exist in the electron cloud and can jump from one orbital to another. an orbital can hold a maximum of 2 electrons. to occupy the same orbital, 2 electrons must spin in opposite directions. electrons are negative and have opposite magnetic fields which allows them to go from a ground state to an excited state.

Explanation:

The Aufbau Principle states that electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels. This ensures the atom has the lowest - energy state.

Answer:

Electrons are added one at a time to the lowest energy orbitals available until all the electrons of the atom have been accounted for.
