On the periodic table, fluorine is the most electronegative element. On the periodic table, its symbol is F.
ATOMIC NUMBER "9"
ATOMIC MASS "18.998404" (19)
NEUTRONS "19-10=9" (9)
Fluorine is corrosive and a pale yellow gas.
The element having greatest electronegativity is Fluorine.
Electronegativity is defined as the tendency of an element to attract electrons towards itself. More strongly an element attracts electrons, more will be its electronegativity and vice-versa.
Electronegativity of Group 18 elements is usually 0 except Xenon which has an electronegativity value of 2.6. These elements have filled valence shell and hence they do not attract electrons towards itself and hence, has no electronegativity.
In a periodic table, electronegativity decreases down the group and increases from left to right in a period.
Fluorine is present at Period 2, Group 17 of the periodic table.
Francium is present at Period 7, Group 1 of the periodic table.
Hence, fluorine will have the greatest value of electronegativity among the given elements.
it's the greatest electron "hogger"
as you get closet to it, the stronger the electro negitivity.
He is halogen : they don't like to gain electrons. they are already stable.
Fr and Rn
are metals as far is I can remember. they would prefer losing electrons.
