thanks guys!! :-) so basically
element- 1 atom only
compound- CHEMICALLY formed with other atoms and ONLY can be seperated with Electrolysis, Heat is involved in the formation of compound( my teacher did not mention anything about the heat stuff O-o)
mixture- formed w/o Chemical help and can be seperated physically( distillation, seperating funnel, sieving)
the examples for the elements,compound and mixture is kinda hard X_X...
the median that u mentioned, @iEthereality the first method which do not involved the table i've already known, but the table method 1 is kinda hard for me actually... and if it's an odd number the reason to add 1 is because to make it an even number right? so it can be divided to 2.. after that im not sure how to do it, i dont get what u mean by comparing the range..
