The electron configuration of oxygen (atomic number 8) is 1s2 2s2 2p4
The noble gas form is [He] 2s22p4
The element silicon (atomic number 14) has the following electron configuration :- Full configuration: 1s2 2s2 2p6 3s2 3p2- Compressed (without all standard script numbers): 1s2 2s2p6 3s2p2- Noble Gas form : [Ne] 3s2 3p2 / [Ne] 3s2p2 (this works because [Ne] symbolizes the electronic configuration of Neon, which is 1s2 2s2 2p6. When added to 3s2p2, it is equivalent to the full electron configuration of Silicon, when neutral.)The electon configuration of silicon is 1s22s22p63s23p2. The abbrieviated electron configuration is [Ne]3s23p2.
Phosphorus To determine an element from its electron configuration, simply add up the superscript numbers (those are the numbers of electrons in each sublevel): 1s22s22p63s23p3: 2+2+6+2+3=15, and find the element with the matching atomic number*. In this case, Phosphorus. *Note: This method is not correct if the electron configuration of an ion is given, as the number of electrons in an ion does not match its atomic number.
You can tell the difference between 1s subshell and 3s subshell using quantum numbers and electron configuration.

This is best explained by an example: The electron configuration of Strontium (Sr) is: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 This can be simplified by using the noble gas that covers the most items. In this case it is Krypton (Kr) which has an electron configuration of: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 Do you see the similarity in the two configurations? This means that you can use [Kr] to represent 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 So the short-handed (simplified) way of writing Strontium is: [Kr] 5s^2 Everything before the 5s^2 was replaced with [Kr] Note: The "^" symbol means the the following number is in the form of a superscript.
The set of numbers that shows the arrangement of electrons in their shells is known as the electron configuration. It is based on the principle that electrons fill the lowest energy levels first before moving to higher energy levels. The electron configuration is typically represented by a series of numbers and letters indicating the number of electrons in each energy level and orbital.
(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.
Numbers, according to shells and sub-shells which could be octets or duets.

Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
It is element nitrogen. It has an atomic number of 7 and the valence electron is 5. It needs 3 electrons to complete its octet state. That's why sometimes it has the oxidation number of -3 in ammonia.
Francium and lithium have different atomic numbers, electron configuration, Pauling electronegativity etc.
There is only one valance electron in potassium.
