Answer 2

Therefore the Calcium electron configuration will be 1s22s22p63s23p64s2. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.
