If an element has an atomic number of 15, how many electron shells would be occupied in its neutral atom, and how many electrons would be in its outermost shell?
ChemistryClass 9CBSEAnswered 12 May 2026
Answer
For an element with atomic number 15 (Phosphorus), the electron configuration is 2, 8, 5. Therefore, three electron shells would be occupied, and there would be 5 electrons in its outermost shell.
