Elements, Compounds, and Mixtures Those elements, compounds, and mixtures. ‘Though you might be fearing changes, To form some different substances, And, ‘though it may seem strange, And there’s one thing you can bet – Compounds form from elements, One of life’s permanent fixtures. With mixtures, it’s so different, When they form a compound, Yes, chemicals really matter – Without chemical combination Put salt and water together, There’s no reason for to fret. Their properties all change. Chemicals are everywhere – It will still be salty and wet. Their particles rearranged, There’s nothing new to get As chemicals combine, Those elements, compounds, and mixtures. There are over one hundred elements One of life’s permanent fixtures. From which all things are made. When put together chemically, They always form compounds. It’s jumbled up in mixtures that It’s elements, pure and simple, Yes, chemicals really matter – And they’re all made of atoms But thinking of the usual way Elements are building blocks That can’t be broken down. Chemicals are everywhere – Elements are simple things Nothing simpler, I’m afraid. That chemicals are found, Most chemicals abound. Just as Mr. Dalton said.
