Write down the electronic configuration of the following elements from the given atomic numbers. Answer the following question with explanation.
b. 1H, 7N, 20Ca, 16S, 4 Be, 18Ar Which of these elements belong to the second group?
Please read the guide .
Thanks for contributing an answer!
Avoid writing here -
1H, 7N, 20Ca, 16S, 4 Be, 18Ar
Electronic configuration of atoms ::
Among the given elements, Ca and Be belong to second group. Because both has two electrons in the outermost shell. Thus, these two elements belong to second group.
