8. In terms of chemical behavior, the element Lithium (Li) has: a) More in common with Be than Na since Li has 3 protons and Be has 4 protons. b) More in common with He than Be since He has 2 protons and Be has 4 protons. c) More in common with Na than Be since Li has the same number of valence electrons as Na. d) More in common with Na than Be since Li has the same number of valence electrons as Be. e) None of the above

Solution

c) More in common with Na than Be since Li has the same number of valence electrons as Na.This is why they both are similar and can be used in exchange of one another.
