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.

Does Bohr's atomic model look like an onion?
yes
What does bohrs model of the atom look like?
The Bohr atomic model is similar to solar system.
Who invented the Bohr model and what does it look like?
Niels Bohr created this model; electrons move around the positive atomic nucleus.
What does an atomic mass number look like?
Example: the atomic mass number of uranium is 238,02891 - exprimed in atomic mass units.
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.
