Chemistry - Which substance has the lowest electrical conductivity?
a) AL (s)
b) Al2 O3 (l) (just seperated it out to make it clearer)
c) KCl (aq)
d) HCl (g)
explanation would be extremely useful if you have time
Thank you!!

electrical conduction requires the presence of mobile charged particles
a) AL (s) - conductive-has mobile electrons
b) Al2 O3 (l) (just seperated it out to make it clearer)
conductive - although this is considered molecular it has a high enough ionic character to its bonds that there will be mobile ions in the molten state
c) KCl (aq) conductive - dissociates completely - lots of ions in solution
d) HCl (g) non-conductive - uncharged molecules in gaseous state
the winner is HCl

the 1st one is H--F because of the fact Fluorine is the main electronegative and Hydrogen isn't (i'm extraordinarily particular). the 2d i think is "low melting element" And the 0.33 one is certainly Fluorine. as quickly as lower back, Fluorine is the main electronegative of those listed. It tries so not ordinary to income electrons and accomplish noble gasoline stability-- it needs to have an entire octet in its outer shell and become Neon (Ne).
