The atom is made up essentially of the nucleus and orbitals. The electrons revolve around the nucleus within these orbitals. Writing the configuration depends on how you want to put it forth. If you want to go with the Bohr's model, here's how it is:
The electrons move in specific orbits, which are denoted by K, L, M, N, etc. the first shell is the K-shell. It can hold only two electrons. After this, every shell (L, M, N) can hold upto 8 electrons each. So, for the element Oxygen (O8), the configuration will be : K=2, L=6. For Argon (Ar18), it will be: K=2, L=8, M=8
If you want to go with the more accurate orbital model, here's how it is:
The electrons move around the nucleus in their shells. These shells have subshells and orbitals. The name of the shell is denoted by its number. The shell closes to the nucleus is 1, the next 2, the next 3 and so on. The subshells may be s, p, d or f. Then, the number of electrons present in each subshell is denoted in supersript. Each subshell has different orbitals, each of which can hold two electrons, and the shells have one subshell more at every step(based on the azimuthal quantum numbers) So, for Oxygen, it wil be: 1S2 2S2 2P2 and for Argon, it is 1S2 2S2 2P6 3S2 3P6

Why is the short hand configuration also called noble gas configuration?
The short hand configuration is also called noble gas configuration because it mimics the electron configuration of noble gases, which are chemically stable and have full valence shells. By using noble gas configurations, we can easily represent the electron arrangement of elements without writing out the entire electron configuration.
What is the definition of noble gas configuration?
"Noble gas configuration" means that in writing out an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all of the core electrons together and designate it with the symbol of the corresponding noble gas on the periodic table (in brackets). For example, the noble gas configuration of nitrogen is [He]2s22p3

What is electron configuration of H2SO4?
The electron configuration of sulfur (S) in H2SO4 is 1s2 2s2 2p6 3s2 3p4. This is because sulfur has 16 electrons and the electron configuration follows the rules of filling orbitals from the lowest energy level to the highest.

What is a wrong in 1s22s22p23s2?
There is a mistake in the electron configuration provided. It should be 1s2 2s2 2p6 3s2 instead of 1s22s22p23s2. The correct electron configuration follows the rules of Aufbau principle and the Pauli exclusion principle.
What is an anomalous electron configuration?
An anomalous electron configuration occurs when an atom has a different electron configuration than expected based on the normal rules. This can happen when the atom is in an excited state or there are exceptions to standard electron filling patterns.
