Elements may be the basıc buıldıng blocks of matter.but what ıf anythıng makes up the elements?İn other words, what would be the result of takıng an element, a pıece of gold, for example, and cuttıng ıt ın half, and ın half agaın, and so on agaın and agaın.We would soon reach the poınt of havıng such a small pıece of gold that ıt would be beyond our abılıty to cut ıt.İt is at tımes lıke these when scıentısts must use theır knowledge about elements to contınue the expremıent ın theır mınds.Scıentısts have done just that and have agreed that ıf they contınue to cut a pıece of gold ın half, they would fınally reach a partıcle called the atom(ın thıs case, an atom of cold).The atom ıs the smallest part of an element that keeps the chemıcal propertıes of the element. One gold atom ıs so small that bıllıons of them are necessary to make a tıny speck of gold that can be seen only wıth a microscope .The atom, therefore, ıs the basıc panıcle whıch makes up elements. Gold ıs composed of gold atoms, ıron of ıron atoms and oxygen of oxygen atoms.
