This halogen is astatine.
Halogen elements are part of Group XVII. They have seven electrons in their outer shell. The halogen that is most associated with bleach is chlorine.
Halogen family members, or elements in group 17, have 7 valence electrons.
hydrogen is similar to a halogen as its outer most layer of electrons is almost complete.

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.
Halogens are group 17 elements. They have 7 valence electrons.

There is no halogen that will become anionic. All of the valence electrons in halogens are filled, thus halogens will not react with any other compound or element. Bromine is an element that will form and anion with 36 electrons.
No,. The halogens will gain 1 electron when they react if electrons are exchanged.
Ionic. The metal will donate electron(s) to the halogen that will accept electrons. NaCl, for example.
