Commonly, the electron configuration is used to describe the orbitals of an atom in its ground state, but it can also be used to represent an atom that has ionized into a cation or anion by compensating with the loss of or gain of electrons in their subsequent orbitals.

Yes, but an electron configuration could be that of an ion. The identification of an element depends on the number of protons in its nucleus, so only when the species is also neutral can the electron configuration be used to identify it. Examples 1s2 2s2 2p6 is the electron configuration of Neon but also of F-. Take the superscripts and add them together to get the atomic number and if neutral must be Neon but if negative is that of F-

(Ne)3s2 3p2 is an electron configuration notation that describes the arrangement of electrons in an atom or ion. The (Ne) in parentheses indicates that the electron configuration begins with the noble gas neon, which has the electron configuration 1s2 2s2 2p6. The 3s2 indicates that the next two electrons are in the 3s orbital, and the 3p2 indicates that the final two electrons are in two of the three 3p orbitals. The superscript 2 for each orbital indicates that there are two electrons in each orbital, following the Pauli exclusion principle, which states that no two electrons in an atom can have the same set of quantum numbers. The "sp" notation is not commonly used in electron configuration notation. It is more commonly used in hybridization notation to describe the hybridization of atomic orbitals in a molecule. In that context, "sp2" would indicate that one s orbital and two p orbitals have combined to form three hybrid orbitals, which are used to form sigma bonds with other atoms.

Not exactly. An electron is an actual physical particle with a negative charge. An electron cloud is (generally) a spherical area around the nucleus of an atom that predicts where the electrons might be located.
Chromium has a half filled D orbital so is stable.
Because it is shorter and easier to write. Also saves time when compared to writing the complete electron configuration.
Each element has a specific electron configuration, causing each to have a distinctive color when exposed to fire
