|
Are formed when atoms lose, accept or share electrons |
Chemical Bonds |
|
|
It exist between metal and non metal atoms where metal loses electron/s while non metals accepts the electrons donated by the metal. |
Ionic Bonding |
|
|
When two non metals atoms combine, neither of them loses or gains electrons instead, electrons pairs are being shared by both atoms |
Covalent Bonding |
|
|
Occurs when there is a transfer of one or more valence electrons form one atom to another. |
Ionic bonding |
|
|
Is formed when the valence electrons are not associated with a particular atom or ion, but exist as a cloud of electrons around the ion centers. |
Metallic Bonding |
|
|
Is a separation of electric charge leading to a molecule or its chemical group having an electric dipole moment with a negatively charged end |
Polarity |
|
|
Is a measure of an atoms ability to attract shared electrons itself. On the periodic table it generally increases as you move from left. |
Electronegativity |
|
|
Covalent bond is formed when electrons are shared unequally by two atoms in a compound. The bonded pair of atoms form an ELECTRIC DIPOLE |
Polar |
|
|
Means "two poles" which means that a molecule has one positive end and one negative end |
Dipole |
|
|
Covalent bond develops if both atoms equally share a pair of electrons between them |
Nonpolar |
