The universe, the elements & the Atom, Subsystems of earth

• the universe was filled with gluons and quarks
• Founder of the Big Bang Theory Edwin Hubble
• light elements were born during a process nown as the Big Bang nucleosynthesis
• same atomic number different mass Isotopes
• developed another theory of matter- Democritus
• 
  

  elements with atomic mass numbers 99-118- synthetic elements
• process of producing radioactive elements - nuclear reaction
• experiments with dephlogisticated air - Antoine Lavoisier
• experimented with red mercury calx - Joseph Priestly
• clumping of H and HE - star
• helium to carbon & oxygen - stellar evolution
• 
  

  mass of H and HE - protostar
• all matter consisted of only two elements - 75% H and 25% HE
• Formation of new elements through nuclear reactions - nucleosynthesis
• Isotopes that are not radioactive - stable isotopes
• Four fundamental substances (air, water, earth, Fire) - Empedocles
• two of the best known philosopher Ancient Greece - Aristotle and Plato
• process of producing radioactive elements - nuclear reaction
• invented the barometer - Evangelista Torricelli
• experiments showing that matter consists of lumpy particles - John Dalton
• 
  

  proposed the "plum pudding" - Joseph J. Thomson
• planetary model for hydrogen atom - Niels Bohr
• developed another theory that air and gases consist of tiny particles- Daniel Bernoulli
• H. He, Li, Be, & B were created in the Big Bang
• clouds of H and HE - nebulas
