"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 noble-gas notation and why is it used to write electron configuration?
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 forward. 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.
What is the noble gas notation for h?
There is no boble gas notation for hydrogen and helium. The noble gas notation starts for elements after helium. 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 forward.
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.

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.
What is the NOBLE GAS notation write the electron configuration for the calcium atom?
Noble gas notation is a way of simplifying electron configurations by using the previous noble gas's electron configuration as a starting point. For calcium, the electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2. Using the noble gas argon (1s2 2s2 2p6 3s2 3p6) as the starting point, the noble gas notation for calcium is [Ar] 4s2.
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.

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.
The elements Li and F combine to form an ionic compound The electron configurations in this compound are the same as the electron configurations of atoms in which group?
The electron configurations of LiF will be the same as the electron configurations of atoms in Group 18 (noble gases) because Li will lose its single electron to attain a stable octet similar to the noble gases, while F will gain an electron to achieve a complete valence shell.
