That's the symbol used for a battery. Actually, it's <em>one cell of a battery</em>, and if there's more than one cell used in the circuit, then the same symbol is repeated in the diagram.
The longer line ... on the left side in this picture ... represents the positive ( + ) side of the cell. The short, fat line on the right is the negative side.
This would prove that gold is an <em>element</em>. No matter how far down you
examine it, you never find any particles of anything except gold.
An example of a different case is salt.
-- Imagine you had a block of salt and decided to cut it in half.
-- If you repeated this process, then eventually, at some point, you'd have
a tiny particle of salt in front of you, just like before. BUT ...
-- Just as you were getting ready to cut this one in half, you'd notice that this
particle of salt is different. It's one atom of sodium stuck to one atom of chlorine,
and if you cut it in half, you would not have ANY salt. <span />
This would prove that salt is a <em><u>compound</u></em>, made of atoms of two or more elements.
