Why be and Mg not chemically inactive

  1. May 11, 2006 #1
    Be has 4 electrons, thus the electronic
    configuration is 1s2 2s2
    Mg has 12 electrons, thus the electronic
    configuration is 1s2 2s2 2p6 3s2
    Both Be and Mg have
    closed subshells. Why are they not chemically
    inactive (inert)?

    To be chemically inert, the element needs closed shells, not subshells. Also, in recent years, compounds involving the heavier inert gases (xenon and krypton?) have been formed.
