Build A molecule Workshop

1. Build A molecule Workshop You will build new molecules from the given atoms and molecules. Put the atoms together by making their electron clouds touch. Bonds are when atoms are connected together. In chemical reactions, bonds are broken and atoms are rearranged making new substances.

2. Build A molecule Workshop • A chemical formula tells you how many atoms are in a molecule. • the 2 in H2O goes with the letter in front of it. • there are 2 Hydrogen atoms bonded to one oxygen atom
