Exam Study Guide
Chapter 5 Periodic Law
Advanced Chemistry
5-1
· know all scientists involved in periodic table and what they did
· know Mendeleev’s arrangement of Periodic Table
· know problem associated with Mendeleev’s table (elements out of order) and answer
o know elements predicted by Mendeleev
· know Moseley’s arrangement of Periodic Table
· know periodic law- definition
o know reason for periodicity (same valence e- or electron config.)
· know major groups/ group of elements added to table after Mendeleev’s time (see book!)
· Seaborg- discovered most of bottom 2 rows (transuranium elements)
5-2
· know specific group names
o properties of certain groups- group1 very reactive, etc.
· main group/representative elements
· transition elements, inner transition elements (name of each)
· how the table is divided into types of elements: metals, nonmetals, metalloid
o know the properties of these groups as a whole- metals are hard, good conductors, etc.
· blocks: s,p,d,f
· metallic and nonmetallic character
· be able to number periods and groups
· stairstep line- what it divides
5-3
· know periodic trends (group and period) and be able to explain why this trends occurs
o atomic and ionic radii(AR and IR)- how measured
o know cation and anion- definition, which elements form which type of ion
o size of cation/anion compared to neutral parent
o ionization energy(IE)- definition, trends, successive IEs (1st, 2nd, etc.), large jump in IE at full energy level
o electronegativity(EN)- definition, trends, know most electronegative element (no noble gases)
o reactivity(R)- metals compared to nonmetals
o general statement of trends within the d-block and f-block elements- can be summed up in a couple of sentences (see book if not sure)
Other
· be able to apply trends and rank elements like homework
· be able to label a blank table- NO element symbols!!
