Question

-- Quantum Numbers Adapted from: David M. Hanson, Foundations 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 electron, chemists often think of anatomic orbim region of space in which an electron can be found. Classic 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 describes before of being Symbol Name Principal Angular Momentum Magnetic Representation Size and energy Shape Orientation in space Direction of spin Allowed Values n=1,2,3... 1-0,1,2,...1-1 me--.........+1 -yor+ % Spin 1. 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. 2. Which quantum number identifies the shape of an orbital? 3. As the principal quantum number increases, what happens to the size of a particular type of urbital? (the s orbital, for example)

Answer 1

The orbitals sipid, are things based on their Angular momenfium quentum spin quantum Number. distinguised by theses tour principal quantum No, Number, magnetic quentrum Numbers 1. Son The shape of quantum Number which identifies the shape of orbital in Angular momentum quantem Number As the the principal quantum Number increases, size of a particular orbital also increases.
