MOLECULES AND ATOMS

THE MOLECULE OF A SUBSTANCE AND THE SMALLEST PARTICLE FOUND IN THAT SUBSTANCE AND AN ATOMS IS THE SMALLES PART OF AN ELEMENT THAT RETAINS ALL ITS PROPERTIES.THE MOLECULES OF A SUBSTANCE ARE ALL THE SAME TO EACH OTHER AND DIFFERENT FROM THE MOLECULES OF ALL THE OTHER SUBSTANCES

CHEMICAL ELEMENT

1. A CHEMICAL ELEMENT IS A SUBSTANCE THAT CANNOT BE BREAKDOWN INTO SIMPLER SUBSTANCES AND CORRESPONDS TO A CERTAIN TYPE OF ATOM

1. AN ATOM IS THE SMALLEST PART OF AN ELEMENT CHR PRESERVES ALL ITS PROPERTIES

THERE ARE 92 CHEMICAL ELEMENTS AND 92 TYPES OF ATOMS. Each element corresponds to a name and a symbol

Here you can include arelevant data to highlight
