Answer: Neon
Explanation: The second period involves elements with n =2 i.e. the elements have electrons in second shell. The element with filled s and p orbitals will have outer electronic configuration [tex]2s^22p^6[/tex]
Thus the element with filled orbital will be a noble gas. It will have total of 10 electrons and the element will be neon with complete outer electronic configuration will be:
[tex]1s^22s^22p^6[/tex]
