Major Ideas
Symbol: FeColor: GrayClassification: Metallic Found most:
most abundant element
In the human body
I am most useful when I am mixed with
small amounts of carbon to produce steelEarliest know use: 2500 B.C
IronSlide5
Major Ideas
Symbol: CoColor: GrayClassification: Metallic Found most:
G
lass
Objects for beauty
Earliest know use: 1735
CobaltSlide6
Major Ideas
Symbol: NiColor: GrayClassification: Metallic Found most:
Makes materials stronger
Batteries (not so much anymore…)
Earliest know use:
1751NickelSlide7
Magnetism &
AtomsSlide8
Three major ideas:
An invisible forced caused by certain solids and fluidsMagnets= have north and south poles that can attract each otherNeither of the Earth’s magnetic poles actually at the geographic polesMagnetismSlide9
b) Properties
Sprinkle iron filings near me and you’ll see… I am surrounded by an invisible field of forceMy power is from the spin of their electronsMagnetismSlide10
c
) Current uses of magnets CompassATM cards/ Credit CardsSecurity tagsd) Earliest known use: 2 B. C
MagnetismSlide11
There are more than: 150“Fundamental particles” which means: Cannot be broken down into smaller particlesRuled over by:
Strong and weak forces
AtomSlide12
Three major ideas: All matter in the universe is made up of117 different types of atomsStable character with a long historyScientists discovered
: the atom took 100 years to discover
Atom “Atom Family”Slide13
c) Description: Mostly I’m
spaceMade up of:Protons: positive particleNeutrons: neutral particleElectrons: negative particle
Atom “Atom Family”Slide14
Three major ideas: Fundamental particle found orbiting an atom’s nucleus“always” as many electrons as protons in an atomA feather-light tyke that packs a tremendous punchElectronSlide15
b) Charge is:
negativec) I normally zip around outer regions of an atomd) I always return and I can’t help it- with a negative charge equal to a proton’s positive charge. I am constantly drawn toward the nucleus. e) Date of discovery: 1897ElectronSlide16
Three major ideas: Subatomic particle found in the nucleus of an atom“loves” to be at the center of thingsNOT a fundamental particle- made of quarksProtonSlide17
b) Charge is:
positivec) I cannot bear to be around other protonsd) I am a big fellow, around 2,000 times bigger than an electrone) Date of discovery: 1918ProtonSlide18
Three major ideas: This fat fellow is the last piece of the atomic puzzleOnly affected by the strong force and gravityMade up of quarks and is the key to nuclear chain reactionsNeutronSlide19
b) Charge is:
neutralc) I am a calming influence- without me, protons would repel one another and fly off to infinityd) Date of discovery: 1932Neutron
