Relate the order of activities of the halgens to their position on the Periodic Table, and if there a similar trend presents itself with teh metals in the activity chart.

Halogens get more reactive as you go up the group (as the atoms get smaller) and metals get more reactive as you go down a group (as the atoms get bigger).

The higher on the Periodic table, the more active the halogen.
This is because halogens seek to gain one electron. TRhe smaller the atom, the closer the nucleus is to the outer shell where it can pull in the electron. Therefore, fluorine is the most active halogen.
It is basically the reverse with metals. They seek to lose an electron to become an ion. The larger the atom, the less influence the nucleus has to hold back that electron. So Francium is the most active metal.

The alkaline (far left) get extra reactive as you bypass down. Lithium will choose the flow on water, yet reacts. sodium if chilly won't seize hearth, Rubidium, Cs, virtually explode in water Francium would desire to truly be something. (It perhaps yet another liquid) Aluminum is extremely reactive, yet by using fact it kinds Sapphire with air, it does not proceed to corrode. that is going to will react in water and lye. The hydroxide assaults the oxide then the water reacts with the aluminum. Print out a huge Periodic table, positioned it on the wall and learn it very intently. this could be very useful to you later.
