Key Stage 3
Meaning
The Periodic Table is a chart listing all the known elements arranged in order of Atomic Number and in columns of elements with similar properties.
About The Periodic Table
- The modern Periodic Table was arranged by a scientist called Mendeleev. Other's had tried to arrange all the elements before, but Mendeleev was the first to arrange by both Atomic Number and chemical properties.
- The columns of the Periodic Table are called Groups.
- The rows of the Periodic Table are called Periods.
 |
Groups
- The elements are arranged groups of similar Chemical Properties.
- Elements have similar Chemical Properties when they have the same number of electrons in the Outer Shell.
 |
Periods
- The periods are arranged by the number of Electron Shells.
