Carbon group or group 4a

Carbon Groupor group 4A

By Rocco Campanale and Nick Decristofano


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


Conclusion

Conclusion

  • 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
