Bohr's model: Extreme atoms
When the laser pulse slammed into the neon atoms in that experiment ... 1913 looked like a miniature Solar System, with electrons arranged in concentric orbits around a positively charged nucleus. In Bohr's model, electrons were point-like particles ...
What’s the Difference Between Physics and Chemistry?
An off-line question from someone at Seed: Fundamentally, what is the difference between chemistry and physics ... how the protons and neutrons are arranged in the nucleus, save for where that affects how the electrons are arranged (in things like the ...
Electron arrangement of the first 20 elements
Electrons are arranged in shells at different distances around the nucleus. As we move across each row of the Periodic Table the proton number increases by one for each element. This means the number of electrons also increases by one for each element.
The Geometry of Snowflakes -- Oxygen Structure
Like the 120 degree angle formed regularly in snowflakes, liquid or gaseous water has a consistent angular formation. With the hydrogen atoms always sharing two sets of two electrons on one side of the Oxgen nucleus ... around the ring. This crystal ...
How Many Neutrons and Protons Can Get Along? Maybe 7,000
This illustration of the nuclear landscape shows atomic isotopes arranged by an increasing number ... "Remarkably, we don't what combinations of neutrons and protons can make an atomic nucleus. We are not sure how many elements can ultimately exist ...
