How many valence electrons does carbon have? So you'll oftentimes see fluorine as a fluoride anion, so it has a negative one charge. This characteristic makes them more … In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair. These atoms need one more electron in order to have a stable octet. 0 2 8 7 All Rights Reserved. 0 0. have 7 valence electrons. All halogens have seven valence electrons, but as the atomic size increases, the attraction between the nucleus and these outer electrons decreases. Anonymous. Halogens are highly electronegative, with high electron affinities. Halogens are the elements of the group 17 of the periodic table: F, Cl, Br, I, At. packerwidow. A halogen is located in group 17 of the periodic table, so the electron configuration for the valance electron would be ns2np5 (n=energy level). As you remember, valence electrons are the ones in the outermost shell. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals. Relevance. 1.

How many valence electrons does a halogen atom have? Answer: D. 7 Explanation: The halogens are found in Group 7 of the Periodic Table. What is probably the most significant feature of halogens is that The heaviest of the stable halogens, it exists as a lustrous, purple-black non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius. Therefore, as the halogens are all in group 7 of the periodic table, they all have 7 electrons in their outer shell. The halogens are a series of non-metal elements from group 17 of the periodic table (formerly VII). 7. Matthew_Fayoyin. The halogens have how many valence electrons? Zel.
