Navigating the Table Element: The “building blocks” of matter – cannot be broken down by physical or chemical means

Periods: Rows (go across) on PToE GROUPS: Groups (Also called “Families”): Columns (go up and down) on PToE They are numbered 1-18 Group 1 has Hydrogen at the top Group 18 has Helium at the top They can also be grouped A and B with an accompanying Roman Numeral Periods: Rows (go across) on PToE They are numbered 1-7

Quick Check: What’s the Element? Group 2, Period 5? Group 16, Period 4? Group 3A, Period 2? Group 5B, Period 5?

GROUPING ELEMENTS There are several ways the elements can be sorted… Before I tell you, let’s think about a few different substances and see how they act.

Metals, Nonmetals, Metalloids Good conductors of heat and electricity High luster (shine) Ductile, malleable. Non-Metal Poor conductors of heat and electricity Dull and brittle

Metalloids Metalloids Located on the “staircase” of the periodic table. Generally have properties similar to metals and nonmetals Mediocre conductors of electricity Aka “semiconductors”

Solid, Liquid, Gas These is another way we can classify elements… whether they are solid, liquid, or gas at room temperature.

Color-Coding Using colored pencil or crayons, take 10 minutes to color your periodic table by metal, metalloid, or non-metal. Find some way (a symbol or shape or some way you will understand) to identify elements based on whether they are solid, liquid, or gas at room temperature.

Mg, Si, Cl, Cd, Rb, Pb, Al, Sb, Ar, O, W, Br For the elements listed above, what is/are: Metals Nonmetals Metalloids Poor conductors of electricity Gases at room temperature HOMEWORK (have them copy)
