reallllly stumped here, please help! Using the Periodic Table of the Elements with Atomic Mass to list the densities of all the metals in Group 2A, discuss the trend that exists in Group 1A in terms of density. Why does this trend exist?

    compared to the density of 1A group in the same period are lower than the density of 2 A groups :)
