Part B Consider that a single box represents an orbital, and an electron is represented as a half arrow. Orbitals of equal energy are grouped together. The orbital diagram will be valid if it follows both Hund's rule and Pauli's principle. Sort the various orbital diagrams based on whether they are valid, whether they break Hund's rule, or whether they break Pauli's exclusion principle. Drag the appropriate items to their respective bins.

How many nodes are there in the 1s, 2p, and 3d orbitals? How many nodes are in a 4f orbital? Match the words in the left column to the appropriate blanks in the sentences on the right. a node two nodes four three more less five two Reset Help The 1s orbital does not have any nodes. The 2p orbitals have the 3d orbitals have a cloverleaf shape, with lobes of electron density around the nucleus and two perpendicular nodal planes. The f orbitals are even more complex. The number of nodes (and nodal planes) depends on the specific orbital, but there will be than for s, p, or d orbitals. at the nucleus. Four of

List these electron subshells in order of increasing energy. 3p, 3s, 2s, 2p Note for advanced students: you may assume these subshells are all in an atom with many electrons, not a hydrogen atom.
