Important Dates• Projects Due

• Research = Tuesday 12/11• Project = Tuesday 12/13

• Unit Test– Monday 12/16

Activator Write and answer the question

in your notes section:• The two rows on the

most bottom part of the periodic table have been “pulled out: of order.

• Why are these rows pulled out of the main periodic table?

SPS4: Students will investigate the arrangement of

the Periodic Tableb. Use the periodic table to predict

the above properties for representative elements

EQ: What are the representative elements and their location on

the periodic table?

Metals, Nonmetals, Metalloids

• Metals - conductors of electricity, luster, malleable, reactive, solids

• Nonmetals - not conductors of electricity, reactive & non-reactive, gases, liquids and solids

• Metalloids - semiconductors, solids

8 types of Representative Elements• Alkali metals

• Alkaline Earth Metals• Transition Metals

• Metalloids• Halogens

• Nobel Gases• Lanthanide/Actinides

• Synthetics

Alkali Metals• Group 1

Li, Na, K, Rb, Cs, Fr• Highly reactive with

water, can burn in air• Soft, shiny gray • True metals

Alkaline Earth Metals• Group 2 Be, Mg, Ca, Sr, Ba,

Ra• Harder, denser,

stronger than alkali metals

• True metals

Transition metals• Found in middle of chart• Familiar metals; not as

reactive as true metals• Groups 3 to 12

Metalloids• Have properties of metals

and nonmetals• Found along “stair-steps” • Aka: semiconductors,

semimetals.• Used in computer chips,

can “print” electric circuits• Ex: silicon

Halogens• Found in group 17

F, Cl, Br, I, At• Gases (Br liquid) and

highly reactive• Like to react with metals

from groups 1 & 2

Nobel Gases• Group 18

He, Ne, Ar, Kr, Xe, Rn• Inert gases - aren’t

reactive with other elements

Lanthanides and Actinides• Found “pulled” out on the

periodic chart• Used in TV, computers• Radioactive and used in

nuclear energy plants and for bombs

Synthetic Elements• Produced in

laboratory• Technetium and

Promethium• Used in “xray”

machines

Summarizer
