The atomic theory has been developing and changing for over two thousand years. The atomic theory timeline shows the theories of the atom's construction over those years. Although we are rather confident in the current model of the atom, in the future, we may look back on this time as jus...
Timeline Description: Atomic theory is the scientific theory of the nature of matter. The theory states that matter is made up of small particles called atoms. Prior to this theory, matter was thought to be able to be divided into any small quantity. The word atom is derived from the ...

Atomic Structure and Timeline Objectives: Describe the process why which the atomic structure was discovered Describe what an atom is an what makes it up. Identify differences in protons, neutrons and electrons Democritus 400 BC Proposed that matter was composed of tiny indivisible particles Not based...
Summary: Timeline of the atomic structureTopic 2: Atomic StructureCurrent model of atomic structure The current model of the structure of an atom is as follows:The nucleus contains protons and neutrons, which are located at the center of the atom. Electrons orbit the nucleus in shells, which ...
Change the timeline from the past into the future. Change the location from Europe and the Mediterranean to a spiral arm of our galaxy. Replace sea-going ships and airplanes with combat starships. Replace fortified islands with orbital fortresses. Change the names of the various factions to new...
Bohr Model In 1913, the Danish scientist Niels Bohr proposed a model with each electron in a specific energy level. Bohr Model According to Bohr’s atomic model, electrons move in definite orbits around the nucleus, much like planets circle the sun. These orbits, or energy levels, are locate...
Given an infinite timeline, even the mightiest of Empires become their own museums. Coda Murder Hobos picked through the ruins of Empire. Those ruins contained the loot, weapons, spells, and armor of an enlightened age. They were full of undead armies of Empire, ancient survivors plotting to ...
, but as indicated in the above timeline, it represented a technical level of spectroscopy that had been reached some 70 years earlier. I faintly also recall some “MIT wavelength tables” in the same library. Because nobody there felt knowledgable enough to teach atomic physics beyond the ...
