Question

write the electronic configuration of chlorine and magnesium on the base of sub-sell and also write down their position in periodic table..

Answer 1

Answer:

Electronic Configuration of chlorine is 1s^2,2s^2 2p^6 , 3s^2 3p^5 and magnesium  is 1s^2 , 2s^2 2p^6 , 3s^2 . The position of chlorine in periodic table is VII and magnesium is IIA ...

Explanation:

Electronic configuration of chlorine is 1s^2,2s^2 2p^6 , 3s^2 3p^5 as chlorine has 17 electrons i.e. its atomic number is 17 and magnesium is 1s^2 , 2s^2 2p^6 , 3s^2 as magnesium has 12 electrons i.e. its atomic number is 12.
