Chemical Bonding Flashcards
Name the 2 types of chemical bonding
Intramolecular bonding and intermolecular bonding
What is intramolecular bonding
This is bonding within a molecule
Name the tree goes of intermolecular bonding
Non polar covalent , polar covalent , ionic bonding
What is intermolecular bonding
This is bonding between molecules.
Name the three types of intermolecular bonding
Van der waals ( weakest )
Dipole - dipole ( medium )
Hydrogen bonding ( strongest )
What is ionic bonding
The force of attraction between oppositely charged ions in a compound.
What is covalent bonding
The sharing of electrons between two or more elements
What is VSEPR
Valence shell electron pair repulsion theory
What is valence
Outer energy level
What does the VSEPR theory states
This theory states that the shape of a molecule depends on the numbers of pairs of electrons around the central atom
Properties of bonding pairs
Usually one electron from each atom in a bond.
The electrons in a bonding pairs have opposite spins this is why they can come together .
What is bonding pairs
Involved in a bound
What are lone pairs
These are pairs of electrons not involved in a bond.
Properties of lone pairs
Lone pairs have a greater power of repulsion than bonding pairs do.
They push other electron pairs further away from themselves than bonding pairs do.
