Fluorine.
In some specific circumstances, hydrogen can behave partly as an alkaline metal as well as a halogen element. This is due to the similarity of the two groups.
Each halogen element has an outer shell that lacks one electron of being full.
8 which is a full outer electron shell. There are two exceptions: Helium(He) and Hydrogen(H) which can only have 2 electrons in their outer shell.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
The halogen with the least-negative electron affinity is astatine. Electron affinity and electronegativities decreases down a group. Since astatine is the last halogen located in Group 17 as you move down the column from fluorine, it has the least negative electron affinity.
Iodine has more radius. It has least attraction for electron.
No,. The halogens will gain 1 electron when they react if electrons are exchanged.
A compound containing one or more of the halogen elements (fluorine, chlorine, bromine, and iodine) but mainly hydrogen and carbon.
In some specific circumstances, hydrogen can behave partly as an alkaline metal as well as a halogen element. This is due to the similarity of the two groups.
Each halogen element has an outer shell that lacks one electron of being full.
Hydrogen, of course. On some periodic tables you still see it in the alkali position and heading the halogen column to.
No, Br is the symbol for Bromine, which is an element in the Halogen group. It can combine with Hydrogen to form Hydrogen bromide (HBr), which is acidic.
The answer is carbon
The outer electrons in bigger halogens are further from the nucleus and so they feel less attraction and so are easier to remove. Therefore, astatine has the lowest ionisation potential of the halogens.
because halogen molecules are nonpolar. So, there is no development of permanent polarity.
*whyHydrogen atoms have only one electron, to fill its outer electron shell it needs one more. (This is an exception to the octet rule.) The elements found in the Halogen family have seven electrons in their outer shell and need one more to fill it (these follow the octet rule).Both Hydrogen and Halogens have similar bonding properties since they all need only one more electron; they can form one single-bond with another atom. If a hydrogen atom is moved then a Halogen is readily able to take its place.For example: Any alkane compound obtained by replacing every hydrogen atom of a halogen is called a perhaloalkane.
No, Bromine is a Halogen
