Question

Is this a correct example of a fluoride ion?

Answer 1

Answer 2

let me ask you something @a1234

Answer 3

okay

Answer 4

an ION IS a negative charge and fluorine is a non metal. if flourine gains an electron why do you think that this is more stable?

Answer 5

I thought it would have a negative charge when it gains an electron

Answer 6

yep remember every element wants to satisfy its octet. octet means the valence electron in the valence shell, holds 8 electrons

when fluorine gains one electron, remember it has 9 protons and 9 electrons. when it gains that electron it now has 10 electrons and 9 protons. because there is 1 more electron than a proton now fluorine has a negative charge -1

But fluorine now has a filled valence shell. and has an electron configuration similar to it's nearest noble gas neon 10 electrons. now that fluorine ion has 10 electrons it's more stable because its octet are filled.

Answer 7

do you know how to write the electron configuration of say neon?

Answer 8

it's (He) 2s^2 2p^6

Answer 9

now compare that to the fluorine ion configuration
