Calcium (Ca) is in group 2 of the periodic table. Elements in group 2 have 2 valence electrons.

Step2: Draw the Lewis - dot diagram

Write the symbol 'Ca' and place 2 dots around it to represent the 2 valence electrons.

Answer:

Ca with 2 dots around it (one on the top and one on the side for example, but the placement of the two dots can vary as long as they are around the symbol).
