the elements
The elements
  • Carbon - C

Uses: Diamonds for jewelry , car parts, graphite for pencils

Found in nature: Carbon and its components are widely distributed in nature.

  • Silicon - Si

Uses: glass, cement, ceramics, most semiconductor devices, silicon resins, seals and oils

Fond in nature: Silicon is found in many dioxide forms

  • Germanium - Ge

Uses: mainly used in transistors and integrated circuits

Found in nature: it is widely dispersed in nature . Germanium ores are rare to find as well.

  • Tin - Sn

Uses: can coating: tin-plated steel containers

Found in nature: Commonly found in the ground 40% of world’s tin located in Malaysia

  • Lead - Pb

Uses: car batteries, coloring element in ceramic glazes, and projectiles

Found in nature: rare in nature, usually found in a ore of zinc, silver, and copper

physical properties
Physical Properties
  • They all have characteristics of metalloids and nonmetals
  • Carbon is either a gas or semisolid, Silicon and Germanium are metalloids, while Tin and Lead are metals
  • Carbon when solid is soft and a dull black
  • Silicon is a semiconductor, with a metallic sheen and very brittle
  • Germanium hard, lustrous, grey and white, very brittle with a diamond crystalline like structure
  • Tin is soft and malleable, silvery white metal
  • Lead is bluish white metal, and malleable is ductile
  • All have relatively high melting points
chemical properties
Chemical Properties
  • All have four electrons in the outer shell
  • Don’t form ions easily
  • Carbon forms bonds with many outer elements
  • CO2 is carbon in it dioxide state it has 2 oxygen\'s attached to it
  • Silicon is electropositive
  • Silicon bonds to oxygen to form silicates
  • Tin resists corrosion from distilled, sea and soft tap water, and can be attacked by strong acids, alkalis and acid salts.
  • Tin also has an oxide film that protects it well
  • Germanium is unaffected by alkalis and acids, except nitric acid.
  • Lead is very resistant to corrosion but tarnishes upon exposure to air.
interesting facts
Interesting facts
  • All life is based on Carbon
  • Carbon has a larger number of compounds then any other element
  • Silicon is the second most abundant element in earth’s crust
  • Germanium crystals used for airport security
  • Tin has been in use since 600 b. c. e.
  • Lead can cause brain damage and disrupt the nervous system
  • The electron configuration for the group always ends in p2, any element that ends in p2 is part of the Carbon Group
  • Each element has many uses throughout the world. Because they are abundant and unique
  • all life is made of carbon.
  • there is a whole science of organic chemistry this is the studies of carbon and the many different bond that it can from
  • The properties of silicon and germanium lead to the computer revolution
  • Tin and lead are important for in many early civilizations like Rome. The reason why these metals were used for many different things
