Chapter 3, Problem 3.28E

Which elements in a given period (horizontal row) of the periodic table lose electrons most easily? Why?

The “Chemistry in Focus" segment The Chemistry of Bohrium discusses element 107. bohrium (Bh). What is the expected electron configuration of Bh?

Using only the periodic table inside the front cover of the text, write the expected ground-state electron configurations for a. the third element in Group 5A. b. element number 116. c. an element with three unpaired 5d electrons. d. the halogen with electrons in the 6p atomic orbitals.

Identify the two atoms with the same number of electrons in their outermost energy level. a. Na/K b. K/Ca c. Na/Mg d. Ca/Na

Which orbital is the first be filled in any atom? Why?
