Periodic Trends Worksheet Name _____ 1. Using the data below, make a bar graph of atomic radius vs. atomic number for Group 2A and for Period 3 of the periodic table. Group 2A Element Atomic Number Atomic Radius Be 4 1.11 Mg 12 1.60 Ca 20 1.97 Sr 38 2.15 Ba 56 2.17 1.2 Periodic . Trends . Multiple. Choice. Review. PSI Chemistry Name_____ Atomic Size . Elements Z and X are compared. Element Z is larger than Element X. Based on this you could say: Element Z is further to the left side of the periodic table. Element X is closer to the top of the periodic table
www.ck12.orgChapter 1. Periodic Trends Science Inquiry Students can gain insight into the trends by making graphs of the various properties as a function of atomic number. Since these graphs are shown and discussed in the ﬂexbook, it is best to do this activity as an introduction to the chapter. The atomic mass periodic trend increases in moving from top to bottom in any given group and decrease in moving along a period. It can also be seen that within a group, there is a fast increase in atomic mass as move from one element to another amongst the first few elements but the increase is not so fast when we do so amongst the last members.
