What does a noble gas electron configuration look like?
A noble gas electron configuration involves representing an element's electron configuration by using the electron configuration of the nearest noble gas preceding it in the periodic table, followed by the remaining electron configuration for that element. For example, the noble gas electron configuration for sodium (Na) is [Ne] 3s¹, where [Ne] represents the electron configuration of neon leading up to sodium.
What is the noble-gas notation?
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 electron configuration of scandium?
The noble gas electron configuration of scandium is [Ar] 4s2 3d1. Scandium has 21 electrons, and the noble gas configuration represents the nearest noble gas to scandium, which is argon with 18 electrons.
Is it acceptable to use the noble gas configuration?
Yes, it is acceptable to use the noble gas configuration to represent the electron configuration of some elements. This simplifies the process by labeling the core electrons as the nearest noble gas configuration and then adding the valence electrons for the specific element.
Is electron configuration for any ion is the same as its nearest noble gas?
No, the electron configuration for an ion is not always the same as that of its nearest noble gas. When an atom loses or gains electrons to form an ion, its electron configuration changes. For example, a sodium ion (Na⁺) has the electron configuration of [Ne], which is the same as neon, but a chloride ion (Cl⁻) also has the same configuration as argon ([Ar]). Thus, while some ions can have configurations similar to noble gases, this is not universally true for all ions.
How does the electron configuration of an ion of a group 1A or 7A element compare to that of the nearest noble gas?
It compares to those of the nearest noble gases by adding electrons to those groups. Hope it`s useful :)

What is the correct noble gas configuration for Co?
Co is cobalt and is not a noble gas. Cobalt is a transition metal. Its electron configuration is [Ar]3d74s2.

What is the stable electron arrangement of sodium after the 3s sublevel electrons been removed?
The stable electron arrangement of sodium after the 3s sublevel electrons have been removed is the noble gas configuration of neon. Sodium loses one electron to achieve a full outer shell, similar to the electron configuration of the nearest noble gas element.
What is the noble gas electron configuration of scandium?
The noble gas electron configuration of scandium is [Ar] 4s2 3d1. Scandium has 21 electrons, and the noble gas configuration represents the nearest noble gas to scandium, which is argon with 18 electrons.

What is the noble gas configuration of boron?
The electron configuration of boron is: [He]2s2.2p1.
Is electron configuration for any ion is the same as its nearest noble gas?
No, the electron configuration for an ion is not always the same as that of its nearest noble gas. When an atom loses or gains electrons to form an ion, its electron configuration changes. For example, a sodium ion (Na⁺) has the electron configuration of [Ne], which is the same as neon, but a chloride ion (Cl⁻) also has the same configuration as argon ([Ar]). Thus, while some ions can have configurations similar to noble gases, this is not universally true for all ions.
What is one way an element can achieve a stable electron configuration?
An element can achieve a stable electron configuration by either gaining, losing, or sharing electrons to attain a full outer electron shell, usually with eight electrons, known as the octet rule. This helps the element to have a stable configuration similar to the nearest noble gas, making it more energetically favorable.
What do the Group IA atoms have to do to become a noble gas configuration?
They have one valence electron. If this electron is lost, the atoms form cations with the electronic configuration of the nearest noble gas.
How many electrons will Strontium gain or lose in forming a noble gas configuration?
Strontium, a group 2 element, will lose 2 electrons to attain a noble gas configuration because it will achieve a stable electron configuration similar to the nearest noble gas, which is krypton. Strontium has 38 electrons in its neutral state, while krypton has 36 electrons. By losing 2 electrons, Strontium becomes Sr2+, and its electron configuration is similar to krypton.
