How many valence electrons does #F# have?

Answer 1

#7#

Fluorine's electron configuration is:

#[He]2s^2\2p^5# or #1s^2\2s^2\2p^5#
Therefore, its valence shell is #n=2#, and so it contains #2+5=7# valence electrons. Since it is one electron away from achieving an electron configuration of neon, a noble gas, would you expect fluorine to have high electronegativity or not?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
