- The periodic Table = C1.1.2
- Elements in the same group in the periodic table have the same number of protons in their outer-most shell.
- This gives them similiar Chemical Properties.
- How reactive they are to oxygen/air and Water.
- Apperance
- e.g. How shiny
- Colour
- Texture
- This gives them similiar Chemical Properties.
- Group 0 / The Noble Gases.
- They are very unreactive
- This is because, they have a stable arrangement of electrons in their outer-most shell.
- (Their outer most shell is full)
- This is because, they have a stable arrangement of electrons in their outer-most shell.
- All noble Gases have 8 electrons in their outershell/ except Helium.
- They are very unreactive
- Group 1/Alkali Metals
- Lithium, Sodium and Potasium react vigorously with Water and Oxygen.
- They produce hydrogen and a strong metal Hydroxide.
- The Metal Hydroxides are strong Alkalis.
- The Alkali Metals react vigorously with oxygen to produce strong metal oxides.
- They produce hydrogen and a strong metal Hydroxide.
- These are very smooth and shiny, but when exposed to oxygen and water they react and become dull.
- Lithium, Sodium and Potasium react vigorously with Water and Oxygen.
- Elements in the same group in the periodic table have the same number of protons in their outer-most shell.
