What is the electron configuration called that has 18 electrons in the outer energy level and all of the orbitals filled?

Noble gas configuration

Atoms of most nonmetallic elements achieve noble-gas electron configurations by gaining electrons to become ______ or negative charged ions

Ah, the noble gas configuration! It's like the party where all the cool kids are hanging out in the outer energy level, and all the orbitals are filled. It's the electron equivalent of having the ultimate VIP access. I mean, who wouldn't want to be part of that exclusive electron club? Just imagine those electrons sipping tiny cocktails in their little orbitals, feeling all fancy and stable. It's the epitome of electron luxury, my friend.

The electron configuration that has 18 electrons in the outer energy level and all of the orbitals filled is called the noble gas configuration. This refers to the configuration of an element when its electron arrangement matches that of a noble gas, which has a stable electron configuration. Noble gases have completely filled outer energy levels, making them very stable and unreactive. The noble gas configuration is often used to represent elements that have similar electron arrangements to the noble gases.

The electron configuration that has 18 electrons in the outer energy level and all of the orbitals filled is called the noble gas configuration. It is named after the noble gases, which are a group of elements located in the far right column of the periodic table. These elements have completely filled outer energy levels, making them stable and unreactive.

To determine the noble gas configuration of an element, you first need to identify the noble gas that comes before it in the periodic table. For example, if you want to find the noble gas configuration of sulfur (atomic number 16), you would look at the noble gas before it, which is argon (atomic number 18).

The noble gas configuration is written by using the noble gas symbol in brackets to represent the inner electron configuration, followed by the outer electron configuration. In the case of sulfur, the noble gas configuration would be [Ne]3s²3p⁴, where [Ne] represents the electron configuration of argon, and 3s²3p⁴ represents the outer energy level of sulfur.

So, the noble gas configuration for an element with 18 electrons in the outer energy level and all orbitals filled would be written as [Ne] followed by the configuration of the outer energy level orbitals.
