Just some notes on Group 1,7 and the Transition Metals of the periodic table
Hope they help! :)
Group 1 metals are Li, Na, K, Rb, Cs, Fr
They are called 'Alkali metals' because when added to water to form a solution they create an alkaline solution.
- React easily with water and have low densities so can float on water.
- Soft solids at room temperature with both low boiling and melting points that decrease going down the group.
- When reacting with water they produce hydrogen and a metal hydroxide (strong alkali).
- They lose their outer shell electron in reactions to form ionic compounds in which their ions have a single positive charge e.g. Na+.
- They get more reactive going down the group. This is because the outer electron is less strongly attracted to the…
