  • How many grams in 3.4 x 1023 molecules of H2SO4?

    2. How many molecules are there in 0.40 g of N2I6?


Nuclear chemistry

Nuclear Chemistry


Unstable nuclei

Unstable Nuclei

Often nuclei of very large atoms are unstable…

Unstable Nuclei  Stable Nuclei + Energy


Cause of instability

Cause of Instability

A p+ to no ratio that is not close to 1:1

Example: Polonium (Po) has 84 protons and 125 neutrons

Radioactive

Oxygen has 8 protons and 8 neutrons

Not Radioactive


Nuclear reaction

Nuclear Reaction

  • Reaction that affects the nucleus of an atom.

  • Radioactive decay: Spontaneous disintegration of a nucleus into a slight lighter nucleus.

  • Particles and energy can be emitted.

  • This is called nuclear radiation


92 uranium 238

92-Uranium-238

  • 92 protons and 146 neutrons

  • Radioactive nuclide

  • Undergoes a series of radioactive decay


3 main types of radioactive decay

3 Main types of radioactive decay

  • Alpha

  • Beta

  • Gamma


Alpha particle

Alpha Particle

  • Nucleus of a Helium atom

  • 2 p+ and 2 no

  • Mass = 4, Atomic number = 2


Beta particle

Beta Particle

  • neutron to proton ratio that is too high

  • Mass = 0, number -1


Gamma radiation

Gamma Radiation

  • High energy electromagnetic waves (light)

  • No mass

  • Pure energy

    g


Radiation exposure

Nuclear fission

Nuclear Fission

  • Heavy nuclei splits into more stable nuclei

  • Releases enormous amount of energy


Nuclear reactors

Nuclear Reactors


Nuclear fusion

Nuclear Fusion

2 small nuclei form a larger nuclei, producing a crazy amount of energy.
