single covalent bond.the electron arrangement of chlorine is 2.8.7
the outermost shell lack of one electron to achieve stable electron arrangement.since covalent bonding involves sharing of electrons,one pairvof electros os shared between two chorine atoms to produce a chlorine molecule.

good luck!

the answers are definetily correct .i coppied from chemistry text book from malaysia.

Cl has 7 e- on outer most shell.

In an ionic bonding situation, it will gain one e- to form a Cl- chloride one minus ion.
In ionic bonds there are no references of single double or triple bonds.

but Chlorine also forms covalent bonds with non-metals, so it will share one of its e- with the other non-metal, to form a stable octet shell. so it is a single bond.

if the element has 6 valent e- on outershell, then it will share 2 e with others and form a double bond. eg Oxygen.

ditto for triple bond, try with nitrogen

There are bad answers and some of them can be found with this question. Simple Octet Rule. 2Cl -> Cl-Cl .
Cl is missing one electron for an octet (full shell) (it has 7 in valence shell). Therefore it needs one (and only one) to make an octet. Draw the structure and there is two above, two below, two on one side and one on the other side of each Cl atom. Ignoring the 6 electrons not involved in the covalent bond (not to mention the fact that I can't draw them here) we have Cl. + .Cl -> Cl : Cl (again each Cl is surrounded by three other pairs (6 each) of electrons. Two electrons make 1 single (covalent) bond. Accept no substitutes!
With heavier elements, the question is more difficult!! Like PCl5
(yes thats Cl 5) try drawing the Octet rule with that, sucka! Just remember the exeption tests the rule - or they HAVE been lying to you in school all these years! (alternatively, this simple rule works extremely well for a huge amount of chemistry, but it has its limits, just like the rule "Always do what mommy says") But I digress.

Depend on what it bonds with. Usually, Chlorine have double covalent bond.

Double

single

Cl2 is Cl--Cl

Its electron configuration is 2 : 8 : 7 and so it shares one with its partner making
2 : 8 : 6 + (shared 2) + 6 : 8 :2
and the shared 2 make the single bond.

Cl will have single bond because by one gaining one e- Cl will become stable and that is were all the elements want to be
