Resposta
The halogen with 2 electron shells (EL's) is Fluorine (F). Halogens are a group of elements in the periodic table that have seven valence electrons in their outermost shell. Fluorine is the first element in the halogen group and has an atomic number of 9, which means it has 9 electrons. The electron configuration of Fluorine is 1s² 2s² 2p⁵, indicating that it has 2 electron shells with 7 electrons in the outermost shell.
