1 Unit 5 The Periodic Table

2 I. Development of Periodic Table Periodic law: when elements are arranged in order of increasing atomic number, their physical and chemical properties show a periodic pattern.

3 II. Reading the Periodic Table In each square 1. element symbol 2. atomic number 3. element s name 4. atomic mass Groups or families: elements in columns; have similar properties Periods: rows

4 A. Labeling & Naming Groups 3 ways to number Family Names 1A alkali metals 2A alkaline earth metals 7A halogens 8A noble gases

5

6

7 B. Metals, Nonmetals, Semimetals Metals on left side 1. Luster or shine 2. Conduct heat & electricity 3. Usually solids at room temperature 4. Malleable & ductile

8 B. Metals, Nonmetals, Semimetals Nonmetals on right side 1. No luster 2. Poor conductors of heat & electricity 3. Not malleable or ductile 4. Many are gases at room temperature; some are solids, one is liquid 5. Large variation in properties

9 B. Metals, Nonmetals, Semimetals Semimetals in between Also known as metalloids Properties are in between metals and nonmetals

11 C. Electron Configurations & Periodic Table Hydrogen 1s 1 Lithium 1s 2 2s 1 Sodium 1s 2 2s 2 2p 6 3s 1 All have one electron in the s orbital at the end. Valence electrons: outermost electrons Elements in groups are similar because they have similar valence electron configurations.

12 Figure 11.31: Orbitals being filled for elements in various parts of the periodic table.

13 D. Abbreviated Electron Configurations Atom s inner (core) electrons: represented by the nearest noble gas with a lower atomic number Li [He]2s 1 Na [Ne]3s 1 K [Ar]4s 1 Rb [Kr]5s 1 Cs [Xe]6s 1

14

15 E. The s, p, d, and f-blocks s-block: first two groups, only holds two electrons p-block: last six groups, can hold 6 electrons d-block: in middle (transition metals), can hold 10 electrons start with 3d f-block: on bottom (inner transition metals), can hold 14 electrons start with 4f

16 III. Periodic Trends A. Atomic radius: size of atom; distance from center (nucleus) to outer electrons 1. Atoms get larger going down a group because of increasing energy level 2. Atoms get smaller from left to right across a period because there are more protons in the nucleus to attract the electrons

17 Figure 11.36: Relative atomic sizes for selected atoms.

18 III. Periodic Trends B. Ionic size 1. Loses electrons (+) smaller than atom 2. Gains electrons (-) larger than atom

19

21

22 III. Periodic Trends C. Ionization energy: energy needed to remove an electron Li Li ( g ) ( g) e 1. Decreases down a group 2. Increases across a period (left to right) Small atoms hold electrons more tightly Large atoms lose electrons easily

23

24 III. Periodic Trends D. Electron Affinity: energy change when an electron is gained (+) electron affinity requires energy (-) electron affinity no energy required (loves electrons) 1. Nonmetals usually negative (most) 2. Metals small negatives or positive 3. Noble gases all positive

25

26 III. Periodic Trends Octet Rule: atoms tend to gain, lose, or share electrons in order to acquire a full set of valence electrons. (2 in s, 6 in p of highest energy level)

27

28

29

30 III. Periodic Trends E. Electronegativity: attraction of electrons to atoms involved in a bond Flourine has most (4.0) Cesium & francium least (0.7) 1. Increases from left to right across a period 2. Decreases down a group
