Can any body tell me how a fluorine atom can change into a ion F-?

Question

I have been thinking about this for a while but i cannot figure it out Please Can any body help me out with this question.

Answer 1

yes.....it is true

Answer 2

flourine atom requires only 1 electron to acquire octet

due to presence of 9 protons and due to poor shielding of electrons the electron affinity is high

so it easily acquires ion form

Answer 3

Probably better asked in the chemistry section.

But anyway.

Fluorine's 1p orbital has 5 electrons at a neutral state.  Gaining an electron (and hence F-) gives it a full 1p orbital of 6 electrons, which is much more stable.

Answer 4

flourine atom requires only 1 electron to acquire octet

due to presence of 9 protons and due to poor shielding of electrons the electron affinity is high

so it easily acquires ion form

Answer 5

By accepting one electron. A fluorine atom has 7 electrons on its outermost shel so it needs 8 to become stable.
