The number of electrons in the valence shell of a halogen is 7. What is probably the most significant feature of halogens is that they all are one electron short of the number of electrons required to fill their valence shells, eight. That means they will have similar chemical properties, i.e., they all are on the lookout to borrow one electron.
7 valence electrons
It's 7
Halogen family members, or elements in group 17, have 7 valence electrons.
Iodine has 7 valence electrons like the other halogens.
All halogen elements have 7 valence electrons (group 17): F, Cl, Br, I, At.
yes,manganeese is halogen because halogens have 7 valence electrons and mn has atomic no. 25 i.e. it has 7 valence electrons in its shell. -Abhey Gupta -Xth E -Police DAV Public SCHOOL
Fluorine is a chemical element in the halogen group. It's electron structure is 1s2 2s2 2p5. That means that it has 6 valence electrons.
Halogen family members, or elements in group 17, have 7 valence electrons.
7
Halogens each have 7 valence electrons.
Halogens are group 17 elements. They have 7 valence electrons.
7 electrons are on the outer (valence) shells of all halogens
Fluorine is a halogen. All halogens have 7 valence electrons. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals.
halogen NOTE added by Dr.J.): A halogen doesn't have a few valence electrons. They have 7 valence electrons.
the number of electrons will depend on the halogen under consideration. But all halogens have 7 valence electrons
Iodine has 7 valence electrons like the other halogens.
