google it and type 'periodic table, first twenty elements'\nn u'll get sumthing, far quicker than lettin sum1 write them up 4 u.

This is an answer I gave a few weeks ago. It helped me to get from failing Chemistry to University....maybe it will help you to understand the periodic table as well.\n\nMy Chemistry teacher taught me a great story which helped me learn the elements, which groups they were in, which periods, how many electrons they had etc and resulted in me going from a grade F to B. Every kid should learn this.\n\nHorrible Hairy Little Begger Boys Catch Newts On Friday Near Naples, Magnificent Albert Sits Planning Some Clever Arrangement Keeping Calm.\n\nOk, looks crazy until you break it down;\n\nH He Li Be B C N O F Ne Na, Mg Al Si P S CL Ar K Ca\n\nThen put it into the table\n\nH\nHe\nLi Be B C N O F Ne\nNa Mg Al Si P S Cl Ar \nK Ca\n\nYou will need to line them up because Yahoo has left align, but the trick is the story. \n\nThe groups 1-8 tell you how many electrons are in the outer shell, the periods tell you how many shells etc\n\nHope this helps!

pull out your periodic table and this becomes very easy.  elements have an oxidation # of 0.
