In multielectron atoms many of the periodic trends can be explained in terms of Z a r Consider the following statements and discuss whether or not the statement is true or false. a. Electrons in a p orbital are more effective than electrons in the s orbitals in shielding other electrons from the nuclear charge. b. Z a r for an electron in an s orbital is lower than that for an electron in a p orbital in the same shell. c. Z a r is usually less than Z. d. Electrons in orbitals having l = 1 penetrate better than those with l = 2 . e. Z a r for the orbitals of the elements Na( 3s ), Mg( 3s ), Al( 3p ), P( 3p ), and S( 3p ) are in the order Z a n ( N a ) < Z a n ( M g ) > Z a n ( A I ) < Z a n ( P ) > Z a n ( S ) .
