models

Plum Pudding model

This is an model proposed by JJ Thompson. He said that the outer circle is the positively charged nucleus and the inner pieces (plums) are the negative charged electrons.

Rutherford-Bohr model

This model shows the nucleus and protons in center with the negatively charged electrons rotating in certain rings around it. This shows generally where an electron is but not exact.

Planetary Model



This model not only shows the electrons orbiting around the nucleus, but it shows the different types of orbitals. This made a better resolution model of an atom and lets the viewer see a more real life shot. this shows the S P and D orbitals.
