Bags of Reactions * Problem/Purpose * Background Information: The Law of Conservation of Mass was created by Antoine Lavoisier in the 18th century. This law stated that mass could matter could neither be created nor destroyed. During a reaction the bonds of the reactants are broken and form new substances. As stated in the Law of Conservation‚ matter can neither be created nor destroyed; because of this the products should have the same number and type of atoms as seen in the reactants

Metals and Halogens reactions Elements such as fluorine‚ chlorine‚ bromine‚ iodine‚ and astatine belong to Group 7‚ Halogens. At room temperature‚ fluorine is a yellow gas‚ chlorine is a pale green gas‚ bromine is a red liquid‚ and iodine is a purple solid. Astatine is a radioactive element‚ therefore it exists only in small amounts. All the halogens exist in diatomic molecules. They have high ionization energies and are the most electronegative elements. Their electron configuration ns2 np5 make
