What are the oxidation numbers of Na and Cl?
The oxidation number of Na is +1, as it tends to lose one electron to achieve a stable electron configuration. The oxidation number of Cl is -1, as it tends to gain one electron to achieve a stable electron configuration.
What is the electron configuration of a neutral copper atom?
The electron configuration of a neutral copper atom is 1s2 2s2 2p6 3s2 3p6 3d10 4s1. Copper is an exception to the normal electron configuration pattern because it contributes one electron from the 4s orbital to have a full 3d orbital.
What is the electron configurations of silicon?
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.
What is this electron configuration 1s22s22p63s23p64s23d104p6?
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.

How does noble gas notation simplify writing electron configurations?
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.
What electron could have quantum numbers n 2 l 1 m?
L-1 electron configuration
What is the set of numbers that shows the arrangement of electrons in their shells?
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.
what is (Ne)3s2 3sp2?
(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.
In an electron configuration what are the electrons represented by?
Numbers, according to shells and sub-shells which could be octets or duets.
What is the the electron configuration of N?
1s2 2s2 2p3 (the numbers at the end of each little thingymabober are smalll like exponents!)
What is the relationship between the electron configuration of an element and the period in which that element appear in the periodic table?
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.
How you know that you have the correct total of number of electrons for 1s2 2s2 2p3?
To find the total number of electrons in the configuration 1s2 2s2 2p3, add up the superscripts: 2 (from 1s2) + 2 (from 2s2) + 3 (from 2p3) = 7 electrons. By totaling the numbers associated with each energy level and sublevel, you can ensure the correct number of electrons in the electron configuration.
Which of the orbital namely 1p2s2p and 3f are not possible give reason of your answer?
The orbital 1p2s2p is not possible because the electron configuration notation generally does not include numbers in the orbital names. The notation should typically follow the format: principal energy level (n) followed by the subshell letter (s, p, d, f) and the number of electrons in that subshell. The orbital 3f is not possible in the electron configuration scheme for elements up to and including the actinide series. The "f" orbitals appear in the lanthanide and actinide series, but for elements in the main periodic table, the "f" orbitals are not included.
Why doesn't lithium react as well as francium?
Francium and lithium have different atomic numbers, electron configuration, Pauling electronegativity etc.
What is the total number of valence electrons in an atom with the electron configuration 1s2 2s2 2p6 3s2 3p3?
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.
What group of elements do not have an identical outer electron configuration?
noble gases Helium has 2 valence electrons, whereas the rest have 8.
