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.

Why is electron spin important when writing election configurations?
Electron spin is important for writing electron configurations because it determines the direction of the electron's magnetic moment within an atom. This affects how electrons are distributed among different energy levels and sublevels in an atom, ultimately influencing its chemical properties. Without considering electron spin, electron configurations would not accurately represent the behavior of electrons in an atom.
How can you shorten electron configurations to concentrate on the valence electrons?
Writing at the beginning the adequate symbol of an noble gas, in square parenthesis.
How are electron configurations written using the noble gas notation?
"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
Explain what a noble-gas electron configuration is?
The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point onwards. The notation is shorter to write and makes it easier to identify elements. The noble gas notation starts for elements after helium. For example, the electronic configuration of carbon is 1s2 2s2 2p2, whereas its noble gas notation is [He] 2s2 2p2.
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.
Why is noble gas notation used to write electron configurations?
Because it is shorter and easier to write. Also saves time when compared to writing the complete electron configuration.
How does noble-gas notation shorten the process of writing an elements electrons configuration?
In noble gas notation, you don't have to write the electron configuration up to that noble gas. You simply put the noble gas in brackets [noble gas] and then continue to write the electron configuration from that point. It just makes it shorter and easier to write electron configurations for elements with a lot of electrons.
Why is electron spin important when writing election configurations?
Electron spin is important for writing electron configurations because it determines the direction of the electron's magnetic moment within an atom. This affects how electrons are distributed among different energy levels and sublevels in an atom, ultimately influencing its chemical properties. Without considering electron spin, electron configurations would not accurately represent the behavior of electrons in an atom.
How does scientific notation simplify science?
It saves writing out very large or very small numbers in full as for example 1,000,000,000,000 is 1.0*1012 in scientific notation
What are three rules for writing the electron configurations of elements?
Three rules aufbau principle, the pauli exclusion,and the hunds rule

What are the practical uses of scientific notation Why is scientific notation so important in modern-day society Give at least one example?
Tell you what: I'll describe the practical use, and then you can find the example. OK ?The practical use of scientific notation is to greatly simplify the writing, reporting,and remembering of very large and very small numbers.

What are 2 ways of writing numbers?
standard notation and scientific notation For example: 126,000 is standard notation. 1.26X105 is scientific notation.
Notation for subsequent multiple authors in academic writing?
The notation is: "et al.".
