Question

Family 17 or 7B 7 valence electrons F Cl Br I At very reactive Nonmetals They are very reactive because have 7 valence electrons this means they are ALMOST full and can combine with many elements Halogen elements combine with metals to form compounds called salts Family 3 12 1B 8B Metals 1 2 valence electrons Less reactive than alkaline earth metals because they don t give away their electrons as easily Bottom 2 rows are the Lanthanide F this is a Bohr model of F
