Elements may be the basic building blocks of matter, but what—if anything—makes up the elements? In other words, what would be the result of taking an element, a piece of gold, for example, and cutting it in half, and in half again, ad infinitum. We would soon reach the point of having such a small piece of gold that it would be beyond our ability to cut it. It is at times like these when scientists must use their knowledge about how elements react to continue the experiment in their minds. Scientists have done just that and have agreed that if they continue to cut a piece of gold in half, they would eventually reach a particle called theatom (in this case, an atom of gold). The atom is the smallest part of an element that retains the chemical properties of the element. „One gold atom is so small that billions of them are required to make a tiny speck of gold that can be seen with a microscope. The atom, therefore, is the basic particle which constitutes the elements. Gold is composed of gold atoms, iron of iron
atoms, and oxygen of oxygen atoms.
