Electronegativity |
A measure of the tendency of an atom to attract a bonding pair of electrons |
|
|
Covalent bond (2) |
Sharing of at least one pair of electrons by two non-metal atoms
Electronegativity <1. 8
|
|
|
Non-polar covalent |
(pure covalent) An equal sharing of electrons Electronegativity less than 0.5 |
|
|
Ionic bond (2) |
-The transfer of electrons from one non-metal and metal atom
Electronegativity >2 |
|
|
Metallic bonding (2) |
Metal atoms bond together Occurs between a positive kernel and a sea of delocalised electrons |
|
|
Polar covalent (2) |
Unequal sharing of electrons
Electronegativity between 0.5 and 1.7 |
|
|
What type of bond is it if the electronegativity is between 1.7 and 2? (2) |
If a metal is involved, the bond is ionic If only non-metals , polar covalent |
|
|
Why do atoms bond? |
Octet rule To obtain a full outer energy level like noble gases. |
|
|
What are the different kind of interatomic bonds |
Covalent Ionic Mettalic |
