    Answer:

    Both Beryllium and Calcium have 2 valence electrons, i.e. in ther electronic configuration there are 2 electrons remaining in the outermost shell.  Thus their valencies are also 2.

    Electronic Configurations:

    Beryllium (4) : – [2, 2]

    Calcium  (20) : [2, 8, 8, 2]

    Hope it helps

    Thank you for the question

    Edit

    a. both are very reactive

    b. both react readily with elements in group 1

    c. both rarely combine with other elements

    d. both are rare metals
