Default  Page 6

In the last paragraph of the Salty text at the bottom, under number 2. It should say, “groups 1 and 2”… “groups 7 (VIIB) and 12 (IIB),”… “groups 15 and 18”, not “period” in each of these three cases.

Default  page 9 and 10

Both pages repeatedly state that Zeff increases as you go from "top to bottom down the periodic table." Am I incorrect in thinking that Zeff is opposite of the atomic radius trend and it increases from bottom to top and from left to right? I may be misunderstanding what the book is trying to say.
