Calcium is an element with atomic nuer 20. Stating

answered Jun 4, 2018 by aditya23 (-2,138 points) The atomic nuer of Ca is 20 thus its electronic configuration is 2, 8, 8, 2. (i) It is a metal because it has two electrons in its outermost shell and it easily loses these two electrons to acquire inert gas configuration and form +2 ion.
