Periodicity and Properties of

Elements


Objectives*Discover that electron sublevel structure is

responsible for the periodicity of elements; *determine the group and family of an

element;*realize the importance of the periodic table as

a system of organizing elements with varying characteristics

*apply the importance of organizing different things which give them satisfaction and

a sense of orderliness. *use the periodic table to predict the behavior

of elements *relate the number of valence electrons of

elements to their chemical properties; *construct a model of the periodic table;


The Periodic Table and the Elements

What is the periodic table ?What information is obtained from the table ?How can elemental properties be predicted base on the PT ?

Periodic Table Expanded View

The way the periodic table usually seen is a compress view, placing the Lanthanides and actinides at the bottom of the stable.The Periodic Table can be arrange by subshells. The s-block is Group IA and & IIA, the p-block is Group IIIA - VIIIA. The d-block is the transition metals, and the f-block are the Lanthanides and Actinide metals

Summary

Periodic Table: Map of the Building block of matter

Type: Metal, metalloid and NonmetalGroupings: Representative or main, transition and Lanthanide/Actanides

Family: Elements in the same column have similar chemical property because of similar valence electronsAlkali, Alkaline, chalcogens, halogens, noble gases

Period: Elements in the same row have valence electrons in the same shell.


"The periodic table is an icon for science, not just for chemistry, and it reflects deep truths about the elements


Identify what element is being describe in each item

1. The element that belongs to group IA period 2

2. The element that belongs to Group IIIB period 5

3. The only liquid metal at room temperature

4. The only nonmetal in group 1A5. A transition metal that belongs to group VIII B period 5


Assignment

In the following 2x2 crossword, each letter must be correct four ways: horizontally, vertically, diagonally, and by itself. When the puzzle is complete, the four spaces below will contain the overlapping symbols of 10 elements. Use capital letter for each square. There is only one correct solution. 1 2

3 4


Horizontal1-2:two letter symbol for a metal used in ancient

times3-4: two letter symbol for a metal that burns in

air and is found in group 5AVertical1-3: two letter symbol for a metalloid2-4: two letter symbol for a metal used in U.S.

electronics2-3: two letter symbol for a metal used with Zr

to make wires for superconducting magnets.


2. Trend in Atomic RadiusAtomic Radius:

The size of at atomic specie as determine by the boundaries of the valence e-. Largest atomic species are those found in the SW corner since these atoms have the largest n, but the smallest Zeff.


3. Trend in Ionization Potential

Ionization potential:

The energy required to remove the valence electron from an atomic specie. Largest toward NE corner of PT since these atoms hold on to their valence e- the tightest.


4. Trend in Electron Affinity

Electron Affinity:

The energy release when an electron is added to an atom. Most favorable toward NE corner of PT since these atoms have a great affinity for e-.
