There are five halogens found. All of halogens are non metals. Similar thing for all of them is they are non metals.
Halogens have similar properties. All of them form anion.
they have similar properties
It is so because it also resembles the the halogens. The enthalpy of bond dissociation of Hydrogen is quite similar to Halogens. Its properties resemble both alkali metals and the halogens but differ from them too. So, it is not placed with any of them.
Halogens
Halogens: When reacting with halogens, these metals create metal halides. Halide refers to a compound that is one part halogen. These reactions would look similar to
Halogens have similar properties. All of them form anion.

Halogens are all non-metals, they are all very reactive, and they are all colorful.
Halogens Apex ;)
They have 7 valence electrons
I am guessing Choline was a typo, if you meant chlorine, then all of the halogens have similar chemical properties
hydrogen is similar to a halogen as its outer most layer of electrons is almost complete.
Fluorine or Bromine have similar properties to chlorine because both are halogens.
All the elements in the same group as Flourine have similar properties. This group of elements is referred to as the halogens, and is located in group 7.
