Periodic Table Worksheet Answers Where are the most active metals located? lower left Where are the most active nonmetals located? upper right As you go from left to right across a period, the atomic size (decrease / increase) Why decreases nuclear charge As you travel down a group, the atomic size (decrease/increase) why increase energy A negative ion is (larger/smaller) than its parent atom larger A positive ion is (larger/smaller) than its parent atom smaller As you go from left to right across a period, the first ionization energy generally (decreases/increase) Why increase positive charge As you go down a group, the first ionization energy generally ( decreases/increases) decreases Where is the highest electron negativity found? upper right Where is the lowest electron negativity found? lower left Elements of Group 1 are called Alkali Elements of Group 2 are called Alkaline Elements of Group 3-12 are called Transition As you go from left to right across the periodic table, the elements go from (metals/nonmetal) to (metals/nonmetals). metals nonmetals Group 17 elements are called Halogens The most active element in Group 17 is Fluorine Group 18 elements are called noble gases What sub levels are filling across the Transition Elements D and F Elements within a group have a similar number of Valence electrons Elements across a series have the same number of Principal Energy Level A colored ion generally indicates a group As you go down a group, the elements generally become (more/less) metallic more The majority of elements in the periodic table are (metals/nonmetals) metals Elements in the periodic table are arranged according to their atom number An element with both metallic and nonmetallic properties is called a metalloids 1/1
