Question

what is the equation for the formation of fluoride ion from a fluorine atom

Answer 1

Answer:

Fluorine in its elemental state is a highly electronegative element in the periodic table. Fluorine atom has an electronic configuration of 1s

2

2s

2

2p

5

. So, it is one electron less to form a stable octate or to attain a noble gas configuration. So, Fluorine atom gains one electron to change to flouride anion (F

−

) to attain stable octate. This formation of fluoride releases energy so, formula of fluoride ion is exothermic.

please mark me as brilliant please......

Answer 2

Answer:

Explanation:

Fluorine in its elemental state is a highly electronegative element in the periodic table. Fluorine atom has an electronic configuration of 1s² 2s² 2p∧5.So, it is one electron less to form a stable octate or to attain a noble gas configuration. So, Fluorine atom gains one electron to change to flouride anion (F--)to attain stable octate. This formation of fluoride releases energy so, formula of fluoride ion is exothermic.

Hope it helps.
