SI(SILICON)

HISTORY

• 1787 A.L.Lavoisier
• Found in rock
• 1823 Jöns Jakob Berzelius
• The first person to found si as a element

ELECTRON CONFIGURATION

• 1s2 2s2 2p6 3s2 3p2

HOW DOES IT REACT TO OTHER ELEMENT

• Si + 2Cl₂ == SiCl₄(silicon tetrachloride)
• Si + O₂ == SiO₂（quartz)
• Si + 2F₂ == SiF₄(silicon tetrafluoride)

WHAT IS IT USED FOR TODAY

• Cermets(important materiel for space travel)
• Monocrystalline silicon is used to be a semiconductor
• Also, Monocrystalline silicon is used in solar battery
