Chlorine is a Halogen. It is located in Group 7A of the periodic table. Two chlorine atoms bond to form highly reactive chlorine gas, Cl2. Which statement about the bond between the chlorine atoms is correct?
Chlorine has an electronegativity value of 3.0.
Chlorine atom, CL Chlorine atom, CL ----> chlorine molecule, CL
CL + CL ---> CL - CL
differences in Electronegativity: greater than 1.7, 0.5 to 1.7, less than 0.5, = to 0.5
Bond type: ionic, polar covalent, covalent, nonpolar covalent
a
The bond is polar covalent. The electrons are shared unequally between the two atoms.
b
The bond is nonpolar covalent. The electrons are shared equally between the two atoms.
c
The bond is ionic.
d
The bond is metallic.
