Calcium can be found in the 4th energy level (row) of , and in the 2nd group (column). The first two groups (columns) of the periodic table represent the 's' orbital group. This means that the for calcium must end with ##4s^2##. The 4th energy level (row), 's' orbital block, 2nd group (column).
The total electron configuration is:
##1s^2 2s^2 2p^6 3s^2 3p^6 4s^2## or ##[Kr] 4s^2##
The are found in the highest energy level of the electron configuration in the 's' and 'p' orbitals.
In the case of calcium this is ##4s^2##. This gives calcium an 's' orbital with a pair of electrons in its valence shell.
I hope this was helpful. SMARTERTEACHER
