Neutrons have a neutral charge - 0 3 of 7 Where is the Mass number and Atomic number found? The Mass number is the top number and the Atomic number is the bottom number. 4 of 7 What do you get from Ionic Bonding? Metal atoms lose electrons to form positively charged ions, Non-metal atoms gain electrons to form negatively charged ions. 5 of 7 What is Thermal Decomposition? Calcium carbonate breaks down when heated strongly. This reaction is called thermal decomposition. 6 of 7 What is the equation for Thermal Decomposition? Calcium Carbonate --- Calcium Oxide + Carbon Dioxide 7 of 7
