Which element has the electron configuration 1s22s22p63s23p3? A. Scandium B. Arsenic C. Phosphorus D. Krypton
Phosphorus contains 15 electrons hence the electronic configuration given is of phosphorus.Option C is correct.
Answer: The correct answer is Option C.
Explanation:
Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.
We are given an electronic configuration: \(1s^22s^22p^63s^23p^3\)
Total number of electrons = 15
The element which has 15 electrons in its ground state is phosphorus.
Thus, the correct answer is Option C.
