Chapter 10

Chemical Bonding

Atoms are held together by chemical bonds.

Types of chemical bonds

  1. Ionic bonds
  2. Covalent bonds

Need to know the electron configuration, especially valence electron configuration.

Only valence electrons participate in making chemical bonds.

Gases

1-No fixed shape and volume

Gasses occupy the volume of the container.

2-Compressible: Gasses particles can be squeezed together.

3-Uniform pressure on inner surface of a container.

Gas Pressure

P= F / S

P = pressure, F = force, S = surface

Pressure is the force exerted on the unit area of surface

Gas pressure is the force exerted by the gas particle on the unit area of the container inner surface.

Atmospheric pressure

The force exerted by the gases particles of atmosphere on the unit area of earth.

At sea level: greatest atmospheric pressure.

Behavior of gasses

Boyle’s Law

P1V1 = P2V2

Charles’ Law

V1 / T1 = V2 / T2

Combined gas law

P1V1 / T1 = P2V2 / T2

Avogadro’s law

V1 / n1 = V2 / n2
