Atoms

Atoms are teh building blocks for molecules.

We know of 120 different atoms. Each with their own properties and symbol

Periodic table

The numbered rows in the periodic table are called periods. The numbered columns are called groups. If substances consist of only one kind of atom, those substances have similar properties if the kinds of atoms they consist of are in the same group. Therefore, a number of groups have a special name, which you should know:

group 1: alkali metals

group 2: alkaline earth metals

group 17: halogens

group 18: noble gases
