Regents Class
Your 4th Edition Barron's (Blue) Chem review book has some good review questions for Topic 7: The electronic structure of atoms. The questions are on pages 180-182; the relevant questions are numbers 1-35. Answers are found towards the back of the review book (see index).
I will collect the following homework (25 points towards your average) on Monday. It will be a useful review for your upcoming test also, so you may want to do this assignment tonight as a good test prep:
On looseleaf, for the first 36 elements on the periodic table, write the (1) name of the element, e.g. Aluminum, (2) the symbol of the element, e.g. Al, (3) the Bohr model electron configuration of the element ( e.g. 2-8-3) , (4) the quantum mechanical model electron configuration of the element (with s, p, d, etc...e.g. 1s2 2s2 2p6 3s2 3p1), and (5) the orbital diagram (labeled square boxes, with up and down arrows for opposite spin electrons) of the element. For electron configurations and for orbital diagrams, you may abbreviate the kernel/core electrons with the matching previous noble gas (group 18) in brackets, e.g. [Ne] 3s2 3p1.
Your paper(s) should have five columns (portrait or landscape format; landscape might be easier because it is wider than it is long), the first four columns should be much narrower than the last column because the orbital diagrams will take up the most space. Write NEATLY AND CLEARLY.
