• Covalent bonds are between _____________________________________________.
• Covalent bonds are formed when electrons are _____________________ between two atoms.
If two atoms share 4 electrons, they form a ______________________________. If two atoms
share 6 electrons, they form a ____________________________.
• There are two types of covalent bonds: polar and non-polar. Polar bonds have an
electronegativity difference between ___________________________. Non-polar bonds have
an electronegativity difference less than ___________________.
• In polar bonds, the electrons are shared ________________________________. In non-polar
bonds, the electrons are shared ________________________________.
• Covalent compounds can exist in any state (solid, liquid or gas). They have _____________
