The position of all halogens in group 17 in the periodic table shows that halogens have specific characteristics.

Yes, halogens are mostly non-metals and have had certain orbital electrons in their outer room.

However, halogens often have their own features, such
as the tendency to respond with other compounds.

The location of the element astatine in the activity series of halogens:

The location of the element astatine in the activity series of halogens:

# data[].attributes.body
-Astatine is the largest atomic radius because it is less reactive.

-The larger the radius the less desirable it'll have for electrons.

-The lower the potential of astatine to get associate degree electron as a result of the position of the astatine is that the last one.

The periodic trend among the halogen activity series:

-Radius size decreases because the radius moves from up to down.
-Fluorine has the tiniest radius, astatine with the highest radius.

Ionization energy:
-The energy needed to extract one electron from the atom (to conduct a cation)
-As we tend to go down ionization decreases so astatine {85|chemical element|halogen} has an all-time low ionization number.

Electronegativity:

-Electronegativity is the capability to draw electrons to one's self

-When we tend to go down the periodic table with a lower electronegativity of astatine

The relationship between the variable Atomic Radius, Ionization Energy, and Electronegativity:

# data[].attributes.body
There is an inverse relationship between energy from atomic radius ionization and therefore the electronegativity atomic radius.
Consequently, if the atomic radius will increases the energy of ionization and electronegativity decreases.
(The energy of ionization and therefore the electronegativity have an instantaneous relation).
