Using the electronegativity chart, identify the bond type between chlorine (Cl) and another chlorine (Cl) as polar covalent, nonpolar covalent, or ionic. Electronegativities 1A 0 H 2.1 He - 2A 3A 4A 5A 6A 7A Li 1.0 Be 1.5 B 2.0 C 2.5 N 3.0 O 3.5 F 4.0 Ne - Na 0.9 Mg 1.2 Al 1.5 Si 1.8 P 2.1 S 2.5 Cl 3.0 Ar - K 0.8 Ca 1.0 Ga 1.6 Ge 1.8 As 2.0 Se 2.4 Br 2.8 Kr - ionic bond (>2.0) polar covalent bond (0.5 to 1.9) nonpolar covalent bond (0.0 to 0.4)

00:01 Hello, this question it is related to electro -negativity concept.

00:09 So we know that electro -negativity, it is the tendency to attract a shared pair of electron towards itself.

00:16 So here, if there is attraction interaction between two atoms and each atom having the electro -negativity value.

00:31 So as you can see in this chart here, these are the, the, you know, the, elements with mentioned their electro -negativity value here.

00:38 So here, let us suppose a and b, some molecule it is there, they are having some electro -negativity.

00:46 So if this is the molecule here, if the electro -negativity difference, if you talk about here, so if it is greater than or equal to 2 .0, then the bond between those, that is a and b, it should be ionic bond and if it is in the range of 0 .5 to 0 .9 so that will be polar covalent bond and if it is range to 0 .0 to 0 .4 that means it is a non -polar covalent bond so here as we see with the we need to find out the molecule.

01:43 See if we see that is an ionic compound here it is that means the difference should be greater than 2.

01:48 Let us suppose if we take the fluorine or cl molecule.

01:53 Cl and n a it is there.

01:55 So n a cl it is an ionic compound.

01:59 If we see that the difference here cl it is 3 minus n a here it is 0 .9.

02:07 So this will become 2 .1 so this is greater than 2 .0 value.

02:11 So this is an i ionic compound...
