Ionic bonds:
Bonds formed on the basis of the electrostatic forces
exist between oppositely charged ions
Covalent bonds:
Bonds formed between two or more atoms by a sharing of electrons;
polar covalent bonds
re a particular type of covalent bond
the electrons shared by the atoms
are used to represent paired and unpaired valence (outer shell) electrons in an atom. The Lewis structure is used to represent the covalent bonding of a molecule or ion.
Hydrogen bonds:
Hydrogen bonds:
is a type of attractive (dipole-dipole) interaction between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This bond always involves a hydrogen atom. A hydrogen bond tends to be stronger than van der waals forces,but weaker than covalent bond or ionic bonds.
Van der Waals forces:
All atoms and molecules exhibit weak, short-range attractions for one another due to van der Waals forces.These forces are responsible for the condensation of gases into liquids and the freezing of liquids into solid.
