Answer:
Group 7 or the Halogens
Explanation:
The halogens occupies the 7th group on the periodic table. The group is made of F, Cl , Br, I and At.
The elements in this group are the most reactive of all elements. They are very reactive because they have just 7 electrons in their outermost shell and they only require an electron to complete their electronic configuration to produce an octet which typically mimics the stable group VIII elements.
This makes them very highly reactive.
Explanation:
The compound form in this type of combination is an ionic or electrovalent substance.
Some of the properties of xy, an electrovalent compound are;
- they are usually hard solids with a high melting point or liquids with high boiling points.
- they are soluble in water and insoluble in non-polar solvents.
- in molten form or aqueous form, they conduct electric current.
- in aqueous form, their reactions are usually fast.
