♥ what 20 facts about an element can you find using the periodic table?
♥ my chemistry teacher told us today in class that we can find 20 facts about each element using the periodic table. i'm a little confused, can someone give an example and tell me how to find them?is this true about the periodic table of elements? ---grade 10 science?
♥ reactivity of metals increases as you travel down a column. reactivity of metals decreases as you go across a row. reactivity of non-metals increases as you go up a column and increases as you go across a row. and.. if it is true then how come for this equation nano3 k --> kno3 +na, k reacts with nitrate??? isnt k below na in the periodic table making na more reactive then k?? science homework, confused! the equation above was what my teacher gave us as an example. the numbers are supossed to be really tiny like ^2 , i just didnt know how to write it.can some find fast about each one of the elements in the periodic table - 10 points if you do?
