Question

-Quantum Numbers Adapted from: David M. Hanson, FoundationRT of Chemistry, ed, Pacific Crest, 2006. Quantum numbers describe what we refer to as atomic orbitals, While an atomic orbital is a mathematical function describing an clectron, chemits often think of an atomic orbital as a region of space in which an electron can be found Classis pictures of atomic orbitals describe regions where an electron has a 90 % probability of being within the described surface. Quantum numbers are often described as electron addresses that indicate energy level, shape, and orientation in space of the electron.

What are the characteristic shapes of s, p, and d orbitals that distinguish them from one another? You may need to look up pictures in your text. Which quantum number identifies the shape of an orbital? 2. 3. As the principal quantum number increases, what happens to the size of a particular type of rbital? (the s orbital, for example)
