Electronic Structure
Electrons are arranged in different shells around the
nucleus. The innermost shell - or lowest energy level - is
filled first. Each succeeding shell can only hold a certain
number of electrons before it becomes full. The innermost
shell can hold a maximum of…

The Periodic Table
The periodic table is a very important part of
chemistry. It brings all of the chemical elements
together and places them onto a chart. The position of
an element is of crucial importance.

Elements are placed in groups, all of which react in a similar way.

The alkali metals have the following
properties in common:
· they have low melting and boiling points
compared to most other metals
· they are very soft and can be cut easily
