Explain this trend in melting points. Match the words in the left column to the appropriate blanks in the sentences on the right. ResetHelp Moving across the fourth period from Ca to V , the number of valence electrons Moving across the fourth period from \rm Ca to \rm V , the number of valence electrons blank, with \rm V having a total number of blank valence electrons., with V having a total number of Moving across the fourth period from \rm Ca to \rm V , the number of valence electrons blank, with \rm V having a total number of blank valence electrons. valence electrons. More valence electrons up to a maximum of six mean the occupancy of the bonding molecular orbital band , and thus the strength of the metallic bonding . Stronger metallic bonds are associated with in melting points.
