Molecules and Ions

Classification of Matter

Mixtures

Homogeneous

Uniform composition, solutions, air and ink.

Hetrogeneous

Do not have uniform composition, e.g. salad and concrete.

Pure substances

Compound

Made up from atoms of different kinds, e.g. water.

Elements

Made up from atoms of the same kind which is in their simplest form and cannot be broken down further by ordinary means, e.g. oxygen.

Forming compounds

Chemical compounds

Covalent compounds

Moleules

Formed from covalent bonding and it occurs between atoms of non-metals

Ionic compounds

Ions

Formed when atoms combine together through ionic bonding which atoms can give away or take in electrons to form ions.

The periodic table

A table that tells us the symbol, atomic number and atomic mass of elements

Atoms

Atomic Mass

Weighed average of masses of an element's all naturally occuring isotopes

Isotopes

Atoms with identical atomic number but different mass number

The atomic sturcture

Electrons

Nucleus

Proton

Neutron
