Write down electronic configuration of first 20 elements and also ment

1.	Write down electronic configuration of first 20 elements and also mention their valency , block, period and group in the modern periodic table.
Answer» Answer: The ELEMENT is CALCIUM(Ca) (a)2,8,8,2 or (B)It is a METAL (c) (d)calcium is more reactive than magnesium since it has another shell which means it's easier for calcium to lose ELECTRONS, in other words, calcium is more electropositive than magnesium
