An element with the electronic configuration 1s2 2s2 2p6 3s2 3p4 belongs to
- A. group VI of the p block, period 3
- B. group IV of the p block, period 3
- C. group II of the s block, period 3
- D. group VI of the d block, period 4
Explanation
The outermost shell is the third, giving period 3, and it contains six electrons in total across 3s and 3p, giving group VI, while the last electron entered a p subshell so the element is in the p block. The element is sulphur. Counting only the p electrons and answering group IV is the standard error.
