MATTER, CHEMICAL TRENDS & BONDING

1. Ionic vs. Molecular Compounds

1.1. Ionic Compound

1.2. Common Properties

1.2.1. solids at room temperature definite geometries hard + brittle high melting & boiling points conduct electricty as molten liquids not solid conduct eletricity when dissolved in water

1.3. Molecular Compound

1.3.1. Common Properties

1.3.1.1. Molecular substances exist as: gases, liquids & solids at room temperature Variety of textures: waxy- soft low boiling points and melting points Don't readily dissolve in water

2. Polar vs. Non-Polar Molecules

2.1. Polar Molecules

2.1.1. 1 positive & 1 negative charged end

2.2. Non-Polar Molecules

2.2.1. In symmetricl linear molecule positive and negative cancel each other out
