Question

Which element has 7 valence electrons?

nitrogen (N)
neon (Ne)
lithium (Li)
chlorine (Cl)

Answer 1

do you have a periodic chart

Answer 2

neon is a noble gas , so it has valence 8 electrons .
hint, sodium and chlorine make an ionic substance, sodium has 1 valence electron

Answer 3

neon is a noble gas , so it has valence 8 electrons .
hint, sodium and chlorine form an ionic substance, sodium has 1 valence electron and it is a giver. Chlorine has 7 valence electrons and it is a receiver.

Answer 4

giver means it gives up its electron easily

Answer 5

@perl so its lithium I guess xD ...

Answer 6

lithium is in the group A atoms .
no you want chlorine

Answer 7

N=2,5
Ne=2,8
Li=2,1
Cl=2,8,7
so chlorine has 7 valence electrons.
