The red-colored α, β and γ forms are produced from solutions of black selenium by varying evaporation rates of the solvent (usually CS2). They all have relatively low, monoclinic crystal symmetries and contain nearly identical puckered Se8 rings arranged in different fashions, as in sulfur. The packing is most dense in the α form. In the Se8 rings, the Se-Se distance is 233.5 pm and Se-Se-Se angle is 105.7 degrees. Other selenium allotropes may contain Se6 or Se7 rings.

What does bohrs model of the atom look like?
The Bohr atomic model is similar to solar system.
Does Bohr's atomic model look like an onion?
No, Bohr's atomic model does not look like an onion. It represents the atom as a small, positively charged nucleus surrounded by orbiting electrons in fixed energy levels. The model is more complex and based on quantum mechanics principles.
Who invented the Bohr model and what does it look like?
Niels Bohr created this model; electrons move around the positive atomic nucleus.
Does an atomic model look exactly like a atom?
No. The example of it being like our Solar system is strictly for show. The motion and position of the outer shell electrons is unknowable. We have just recently been able to discern the core of an atom.

What did bohrs atomic model look like?
The usual idea of the atomic model is a nucleus composed of protons and neutrons, surrounded by electrons in orbit in shells of increasing diameter. This helps to visualise the difference between atoms. Quantum theory is that this simple model is not accurate, but it does have the virtue of being easily understood.
What did aristotle's atomic model look like?
Aristotle did not propose an atomic model similar to modern atomic theory. He believed in the concept of the four elements (earth, water, air, fire) as the basic building blocks of matter, rather than indivisible atoms. His model focused on the qualities of hot, cold, wet, and dry to explain changes in matter.
What does you look like a model mean in Tagalog?
"Para ka model" is the phrase in Tagalog which means "you look like a model".
