Meet The Lead Zeppelin, a superhero inspired by the elements of the periodic table! Designed with a torso of 82 protons and 125 neutrons, The Lead Zeppelin embodies the properties of lead: malleable, soft, and a dull gray color. His powers include poisoning enemies to damage their nervous system, shapeshifting into any form he desires, and using his "heavy metal" music to deafen foes. As a rock star from Transitron City, he symbolizes the fascinating world of chemistry and the elements, combining science with superhero action.
E N D
Dimitri Mendeleev • Russian chemist who invented the Periodic Table • Organized them in order of increasing atomic mass
Modern Periodic Table • Organized in order of increasing atomic # • 118 total elements • 1-92 are naturally found on Earth • 93-118 are synthetic or manmade
Rows • Horizontal • We call these “Periods” • There are 7 periods
Columns • Vertical • We call these “groups” • There are 18 groups
Metals • Shiny • Malleable- easily molded • Ductile- easily shaped into wire • Good conductors of heat and electricity • Gray or silver color (except Gold & Copper) • Solid at room temperature (except Mercury(Hg) which is liquid)
Non-Metals • Not shiny • Brittle • Do not conduct heat or electricity • Most are gases at room temperature except: • Sulfur, Phosphorus, Carbon, Selenium
Metalloids • Have properties of both metals and non-metals • Semi-conductors such as Silicon and Germanium only conduct electricity under certain conditions • Used in computer chips and calculators
Groups • Alkali metals in Group 1 • Alkaline Earth in Group 2 • Transition Metals in Groups 3-12 • Halogens in Group 17 • Noble Gases in Group 18 Rare Earth metals – Lanthanides and Actinides
Reactivity • Alkali Metals in Group 1 are extremely reactive! Especially with water! • Halogens are also extremely reactive! • Noble gases are inert! Non-reactive!
It’s a bird!, it’s a plane!, no, its… The Lead Zeppelin! • Super hero from the city of Transitron! • His torso is made of 82 protons, and 125 neutrons! His arms and legs are made of 82 electrons!
Super Powers! • He has three super powers: • 1.) able to poison his enemy damaging their nervous system and causing brain disorders! • 2.) He is soft and malleable, meaning he can shape himself into anything he desires! • 3.) Deafens its enemy with his “Heavy metal” music!
What does he look like? • The Lead Zeppelin is a heavy metal rocker! • He carries his electric guitar on his shoulder • He is a dull gray color • He can shape himself into anything he desires but normally he looks like a rock in the form of a man.
