Period 4 includes the biologically essential elements potassium and calcium and is the first period in the d-block with the lighter transition metals. These include iron the heaviest element forged in main-sequence stars and a principal component of the Earth as well as other important metals such as cobalt nickel and copper. It is situated in the second group which is alkaline earth metals and in the fourth period.
In the first three periods there are only main-group or A elements so Group 4 Period 2 must be Group 4A Period 2 and that would be carbon C.

Ask Question 100. In the first three periods there are only main-group or A elements so Group 4 Period 2 must be Group 4A Period 2 and that would be carbon C.
