9. Periods are determined by number of orbitals (outer rings) found in an atomic model Groups are determined by number of electrons found in the outer orbital of an atomic model Name of the element can either be determined by looking at the number of protons which is the atomic number of the element OR using the period and group to locate it on the periodic table Atomic Model In what period would you find this element? In what group would you find this element? Name of element 4 2 3 2 6 7 Calcium Oxygen Chlorine
