You put the number of protons and neutrons in the middle of the first circle (nucleus). The number of protons and electrons is the Atomic number. Round the Atomic Mass and subtract it by the number of protons and you have your neutrons. Draw another circle (shell) around the first one. You can only put up to two electrons in the first one. The next two circles you draw can hold up to 8. The last shell can hold 18.
EG: Neon
There are ten protons, neutrons and electrons. Draw the nucleus first, then write the number of protons and neutrons inside. Draw a shell around the nucleus and place two electrons side by side. Draw another shell around the first one and draw eight electrons around it.

The Bohr model!
cleveland calvilers
yep- pretty sure
Niels Bohr introduced the notion of electronic orbits.
It added on Niels Bohrs model and his research. And anika's cool :D
Niels Bohr proposed a "planetary system" model for the atom.
Bohr model explain these spectra.
Neil Bohrs atomic model is simply called Bohrs model. It states that electrons have a certain amount of energy, so they must follow certain orbits. This is different from the modern atomic model.
The Bohr atomic model is similar to solar system.
it means you smell and need to get a life :D:D x
