Document Summary

Atomic structure=nuclear + electronic nuclear how many protons neutrons and forces between them. Plum pudding model (j. j. thompson) model of atom pudding is + plums are - plum pudding helps explain electroneutrality of atoms. Nuclear model (rutherford) nucleus + very dense small nucleus electrons are - charged particles very small orbiting nucleus. Small + nucleus surrounded by electrons that travel in orbital shape at specific distances from nucleus. Atomic orbital model (heisenberg, broglie, schrodinger) electrons are atomic orbitals that surround nucleus considered as clouds described as standing waves. By sending energy (energy transfer) we can understand their behavior (electromagnetic radiations) The emission and transmission of energy in the form of waves through space is radiation. Wavelength (type/form light) distance btwn corresponding points frequency number of crests or through passing through a point y each second longer wavelength higher frequency. Electromagnetic spectrum range of wavelengths and frequencies radio waves (low frequency high frequency) gamma rays.
