The halogens, or inert gases, have full outer shells. Helium has 2 valence electrons in its outermost shell, and the other inert gases have eight. Wikipedia has a good entry on this: http://en.wikipedia.org/wiki/Valence_electron
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
They share many properties, but one is that they all have 7 valence electrons.
There are 7 valence electrons in elements of group-17. They are called halogens.
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
No. Alkali metals have one valence electrons. Halogens have 7 valence electrons.
It has 5 valence electrons since it's in Group 15 of the Periodic Table
Halogens have 7 valence electrons.
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
Halogens each have 7 valence electrons.
The number of electrons are different from one to another, however all of them have seven electrons in the valence shell.
A fluorine atom has seven valence electrons, as do all halogens.
They share many properties, but one is that they all have 7 valence electrons.
There are 7 valence electrons in elements of group-17. They are called halogens.
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
halogens
no, but lower halogens have different oxidation states.
Both iodine and chlorine are halogens (group 17) and have 7 valence electrons.
