WebDec 29, 2024 · The electron configuration for fluoride ion (F –) ion is 1s 2 2s 2 2p 6. The number of valence electrons available for Fluorine atoms is 7. Fluorine is situated in Group 17th and has an atomic number of 9. The first shell of Fluorine has 2 electrons and the outer shell or valence shell of Fluorine has 7 electrons, hence, the number of valence ... WebThe electronic configuration for the chloride ion is [Ne] 3 s 2 3 p 6, so the last-filled electron is in 3 p. For the 3 p orbital, n = 3, ℓ = 1, and m ℓ can be-1, 0, +1. (The m ℓ can be any of those values because the orbitals are degenerate, so may fill in any order.) 1.
