The atomic nucleus and the cloud of electrons.
Nucleus and electrons
An atom is containing of electrons, protons, neutrons and other sub atomic particles. Normally the two major regions that comprise the view of the modern atom are nucleus and the electron cloud. The electrons are moving in the electron shell and the nucleus provide space for protons, neutrons, and sub atomic particles.
An atomic orbital is a region in an atom in which there is a high probability of finding electrons.
No, H2O2 is not an atom; it is a molecule. H2O2, or hydrogen peroxide, is composed of two hydrogen atoms and two oxygen atoms bonded together. Each hydrogen atom is an individual atom, and each oxygen atom is an individual atom.
If you build an atom using two protons, two neutrons and two electrons you would build an atom of Helium. To be more-precise, this would create Helium-4 the common isotope of Helium.
The two major regions of an atom are the atomic nucleus and the electron rings surrounding it.
Nucleus and electrons
To determine the hybridization of an atom in a molecule, you can count the number of regions of electron density around the atom. These regions can be bonds or lone pairs. Then, use the following guidelines: If there are 2 regions, the atom is sp hybridized. If there are 3 regions, the atom is sp2 hybridized. If there are 4 regions, the atom is sp3 hybridized. If there are 5 regions, the atom is sp3d hybridized. If there are 6 regions, the atom is sp3d2 hybridized.
an atom has two subatomic particles which are neutrons and protons in the nucleus or "center" and electrons surrounding the nucleus in orbitals, "orbit like" regions of space outside the nucleus.
In general, the nucleus and the electron cloud are the two distinct features of the volume of the atom. The nucleus is home to the proton(s) and whatever neutrons are present, and the electron cloud is where the electrons all hang out. The nucleus, with its protons and neutrons, has most of an atom's mass concentrated there. The electrons are relatively far away, and the orbits they describe give the atom its "shape" by defining its volume in space.
The central atom in TeCl2 has a hybridization of sp3 because it has two bonded atoms and two lone pairs of electrons, totaling four regions of electron density. This leads to the formation of four sp3 hybrid orbitals around the tellurium atom.

Because the central atom has two bonded regions (remember that single, double, and triple bonds all count as one charge cloud). In addition to the two bond regions, there is a lone pair of electrons on the central atom, which counts as the third charge cloud.
The hybridization of water (H2O) is sp3, as it has four regions of electron density around the oxygen atom (two bonding pairs and two lone pairs).
Dichlorine monoxide has two bonding regions. It has a bent molecular geometry with a bond angle of approximately 111 degrees due to the lone pair electrons on the oxygen atom.
In CH4, there are four regions of high electron density surrounding the central carbon atom. These regions correspond to the four bonding pairs of electrons in the four C-H bonds around the central carbon atom.
Electrons are located in 'shells' around the core of on atom. They are never inside the core of an atom.
