1s2 2s2: Two of its electrons are in the first s orbital and the remaining two are in the second s orbital.
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.
The Bohr atomic model is similar to solar system.
The basic structure of the periodic table, arranged by increasing atomic number and properties, is unlikely to change significantly in the future. However, as new elements are discovered and our understanding of atomic structure advances, the periodic table may be expanded or refined to accommodate these changes.
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.

the atomic symbol of oxygen looks like this 0
this question need more detail. first of all, a crystal's external appearance is merely a representation of its ordered internal atomic structure. to look at crystal structure in general, I recommend researching the 14 Bravais Lattices. Depending on what crystal you are talking about, its internal atomic structure will be different.
No.
a rod like structure
The answer would depend on how it was made to orbit and the strength of the electrical field.
nothing
Hybridization in brief can be said as inter mixing of orbitals. But you may have questions such as why? where ? when it happens and what exactly it is? Its very simple for example as in your question consider methane. The carbon atom has 2 electrons in 1s orbital and; 2 electrons in 2s orbital and; 1 electron in 2px orbital and; 1 electron in 2py orbital.In methane before carbon atom undergo bonding with hydrogen it undergoes hybridization ,that is 2s orbitals and 2p orbitals combines or hybridizes and for methane it is sp3 hybridization that means an s orbital had combined with 3 of the 2p orbitals (2px,2py,2pz). It has an tetrahedral arrangement (like four corners of a triangular pyramid) of four lobes of angles approx 109.5 degrees(The angle between H-C-H). After hybridization you cannot differentiate s orbital and p orbital.And in that sp3 hybrid each lobe has one electron and all the lobes bond with hydrogen atoms containing single electron.Note that all the lobes must be treated as an orbital such that they can maximum hold only of two electrons.Thus methane is formed as an result of head on collision of sp3 hybrids and hydrogen atoms.

Silicon atoms have a crystalline structure, forming a diamond cubic lattice in its pure form. Each silicon atom is bonded to four other silicon atoms in a tetrahedral arrangement. These strong covalent bonds give silicon its characteristic properties as a semiconductor.
it looks like a jelly-like structure in a form of a circle
