hey can anyone give me any names of alkalis? quite strong ones i need.......
Arrange these in order (the most reactive first):
copper, zinc, calcium or iron???

Quick chemistry lesson for you. (When I first studied chemistry at school I found it really difficult- then it became one of my best subjects).
Everything in the world is made out of 118 elements- yes everything- air-even you-baked beans- trains-everything-until they discover any new ones.
They can be found in the periodic table
http://en.wikipedia.org/wiki/Periodic_table
The columns in this table-(columns go from top to bottom- not across)have elements that share similar properties.
Chemistry is about how these elements react or behave on their own or together when they combine to form compounds.
Each of theses elements has a structure. They have electron shells. Depending on how many electrons they have in their outer shell determines how reactive they are.
Here is a list of how reactive metals are.

So to one of the questions the answer is ;
Calcium is the most reactive, then Zinc, then Iron, then copper.
To you first question
One of the strongest alkalis is sodium hydroxide- you may use this at school- they dilute it a lot though as it can dissolve flesh! If you had a high concentration of it. It is also known as caustic soda.
Calcium carbonate is an alkaline too. (often use in the production of antacids)- to neutralise stomach acid. indigestion

Sodium & Potassium hydroxides.
From the reactivity series:
Calcium, Zinc, Iron & Copper

Alkali, in the form of sodium hydroxide, in its most concentrated form is a solid, and I don't think that I would want to plop a big chunk of NaOH into a container of water. If the caustic is in the form of a solution (such as a liquid drain opener), it really doesn't make any difference. The reason for all of this is that concentrated sulfuric acid is rather viscous and had an extremely high heat of solution in water. Because of these two facts, if you add water to concentrated sulfuric acid, the water tends to skate on top because of the viscosity, and it can generate enough heat to boil the water which might cause the acid to spatter. In the case of dilute acids or of acids other than concentrated sulfuric, it really doesn't matter very much. However in the interests of extreme safety, remember "Add acid to water - that's what you otter (ought to)".

Miss Purdylicious eh? If you are a teacher and you dont know that... I feel sorry for the students.

What is this your homework or assignment or something. If it is then no way am I doing your dirty work!
