• Matter is composed of small particles.
• The molecules interact with one another through

  attractive forces.
• These molecules are always in constant random

  motion.
• The temperature of a substance is a measure of

  the average kinetic energy of the molecules.
• Atoms are the building blocks of matter.
• The stronger the interaction between two molecules,

  the smaller their distance will be.
• Solids have particles with

  strong intermolecular

  forces
• Liquids have intermediate

  intermolecular forces.
• Gases have weak intermolecular forces.
• The solid becomes a liquid in

  a process called melting.
• Vaporization is liquid to gas
• IONIC BOND – Bond between Metal + Non-metal
• COVALENT BOND – Bond between Non-metal + Non-metal
• Intermolecular forces are attractive forces present in between

  molecules.
• Ion-ion interaction is also known as ionic bonds.
• Dipole-dipole interaction occurs when the molecule has polar covalent bonding.
• Dipole is imbalance
• Electronegativity series 0-0.4 it is non-polar covalent
• if electronegativity series is 0.5-1.7 it is polar covalent
• covalent and ionic bond are intramolecular forces
• if electronegativity series is 1.8-4 then it is ionic bond
