Since 4s-orbital has least value of (n+l), therefore ,it will occupy electrons before
3d-orbital.
The order of increasing of energy of orbitals can be calc. from(n+l) rule or 'Bohr bury rule' According to this rule, the value of n+l is the energy of the orbital and such on orbital will be filled up first. e.g. 4s orbital having lower value of(n+l) has lower energy than 3d orbital and hence 4s orbital is filled up first. For 4s orbital, n+l=4+0=4 For 3d orbital, n+l=3+2=5,therefore 4s orbital will be filled first.
Carbon is the sixth element with a total of 6 electrons. In writing the electron configuration for carbon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for C goes in the 2s orbital. The remaining two electrons will go in the 2p orbital. Therefore the C electron configuration will be 1s2 2s2 2p2.
"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

There are many types of rules for electron configuration. Look at the Aufbau principle and Hund's rules.In each orbital there is a maximum of two electrons.In a "s" orbital, there are two electrons.In a "p" orbital, there are three sub-orbitals, each containing two electrons. (Thus containing 6 electrons)In a "d" orbital, there are five sub-orbitals, each containing two electrons. (Thus containing 10 electrons)In a "f" orbital, there are seven sub-orbitals, each containing two electrons. (Thus containing 14 electrons)Look at the Aufbau diagram I linked below.The coefficient represents the orbital. Do not use mathematics to try to solve the configurations.1s2 2s2 2p6 : Neon's Electron ConfigurationThe letter following the coefficient describes which type of orbital it is, being s,p,d, or f.The superscript denotes the number of electrons it contains. If you add 2, 2, and 6, you would get 10, Neon's atomic number.

writing that is imaginative
Writing to inform focuses on providing facts, explanations, and details to educate the audience on a specific topic. On the other hand, writing to persuade aims to convince the reader to adopt a certain viewpoint or take a specific action by appealing to their emotions, beliefs, or values. While informative writing presents information objectively, persuasive writing uses rhetoric and persuasive techniques to sway the reader's opinion.
