2 Page 2 f 12 Unit 5 Ntes 5.1 ORGANIZATION OF THE PERIODIC TABLE AND ELEMENT CLASSIFICATION In the 1860 s rganized the first peridic table by MASS. He recgnized that when elements were arranged in rder f increasing mass, certain similarities in their chemical prperties appeared at regular intervals. Such a repeating pattern is referred t as periidic. In abut 1916, rganized elements by ATOMIC NUMBER because he recgnized that peridic patterns were better fit fr all knwn elements when rganized by increasing number f nuclear charge, i.e. the number f prtns. The mdern peridic table rders elements by ATOMIC NUMBER. Peridic Law The physical and chemical prperties f the elements are peridic functins f their atmic number. Grups (Families) VERTICAL clumns Designated by numbers The Grup number ONE s place represents the # f electrns an atm pssesses. This applies t grups 1, 2, and nly. Example: all elements in grup 16 have 6 valence e Valence electrns are electrns in the OUTERMOST ENERGY LEVEL f an atm. They are respnsible fr. As yu g DOWN each level in a grup, an ENERGY LEVEL is added t the atm. Elements in a grup have similar and prperties Perids Designated by numbers - HORIZONTAL rws Perid number represents in general the number f ENERGY LEVELS Energy Level the space arund an atm s nucleus where electrns are fund based n the amunt f energy they pssess.

6 Page 6 f 12 Unit 5 Ntes 5.2 PERIODIC TRENDS A. Atmic Radius The atmic radius f a chemical element is a measure f the size f its atms and is the frm the nucleus t the bundary f the surrunding clud f electrns. PERIOD TREND (acrss - left t right): As atmic # INCREASES, AR Fr each element acrss a perid, ne prtn and ne electrn are added t the utermst energy level. As NUCLEAR CHARGE increases (nucleus is mre ++), electrns are pulled (ppsites attract) Practice: K / Kr has the larger atmic radius GROUP TREND (dwn - tp t bttm) As atmic # INCREASES dwn a grup, AR Fr each element dwn a grup, an ENERGY LEVEL is added t the atm. Nuclear charge increases, but als increases. SHIELDING as energy levels are added, electrns are less affected by psitively charged nucleus because electrns repel each ther. Practice: Ba / Mg has the larger atmic radius

7 B. Inizatin Energy Unit 5 Ntes Page 12 Inizatin Energy is the energy required t remve the electrn frm an atm (in kiljules) PERIOD TREND (acrss - left t right): As atmic # INCREASES, IE Nuclear charge increases; are held mre t the nucleus Perid Trend Als, uter energy level is clser t being an Practice: Ca / Br has a higher IE Grup Trend GROUP TREND (dwn - tp t bttm) As atmic # INCREASES, IE Outer electrns are in energy levels Farther frm nucleus, mre remved Practice: Na / Cs has a higher IE Challenge: Which element (frm the entire peridic table) has the highest IE?

8 Page 8 f 12 C. Electrnegativity Unit 5 Ntes Electrnegativity is a measure f an atm s ability t anther atm s electrns (n units). Electrnegativity is abbreviated EN. PERIOD TREND (acrss - left t right): As atmic # INCREASES EN. Metals tend t electrns Nnmetals tend t electrns (t fulfill the Rule) Practice: Be / O has a higher EN Figure: Electrnegativity GROUP TREND (dwn - tp t bttm) As atmic # INCREASES, EN Elements at f grup have e clsely held by nucleus because they are clsest t nucleus. Elements at bttm f grup have mre between nucleus and uter e Practice: N / Sb has a higher EN Challenge: Why are nble gases nt EN?

9 D. Reactivity Unit 5 Ntes Page 12 Reactivity refers t hw an atm is t react with ther substances. Reactivity depends n Hw easily electrns can be remved ( ) 2. Hw easily atms grab electrns ( ) Reactivity f Metals lw inizatin energy PERIOD TREND (acrss - left t right):- As atmic # INCREASES, reactivity GROUP TREND (dwn - tp t bttm) - As atmic # INCREASES, reactivity WHY? If IE is lw, an atm is mre likely t lse an electrn, which results in a chemical reactin with anther atm Reactivity f Nnmetals high electrnegativity PERIOD TREND (acrss - left t right): - As atmic # INCREASES, reactivity GROUP TREND (dwn - tp t bttm): - As atmic # INCREASES, reactivity WHY? IF EN is high, the atm takes electrns frm ther atms mre easily, which results in a chemical reactin. NONMETALS higher EN Arrws indicate increasing reactivity. Nble gases are nt reactive.
