    Atoms in the same group (column) of the periodic table have similar properties. This is because all elements in the same group have the same amount of valence (outer) electrons.

    So, any element directly above or below Calcium on the periodic table would have similar properties.

    These would be Magnesium, Barium, Strontium, Radium, and Beryllium.
