They all have a full set of valence electrons.
the elections with the highest energy are in an f sub level. your welcome :))
The valence electron shell of noble gases is full.
Noble gases are inert gases because of a completely filled valence shell,hence they need not to satisfy their valency.
TRUE (apex)
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.
TRUE (apex)
The electron configuration of noble gases is characterized by a complete outer shell of electrons, which makes them highly stable and unreactive. This full valence shell corresponds to the maximum number of electrons allowed in that shell, adhering to the octet rule for most noble gases. For example, helium has a complete outer shell with two electrons, while the other noble gases, such as neon, argon, and xenon, have eight electrons in their outer shells. This stability is the reason noble gases are found in nature in their monatomic form.
Each neutral atom has a specific electron cofiguration.
they are all completely filled in the case of noble gases
Noble gasses are historically known as inert gasses - so true
This statement is generally true. Chemically inert atoms, such as the noble gases, have a full outer electron shell, which makes them stable and less likely to react with other atoms to form compounds.
Ions that are formed when metals gain electrons are called anions. This process allows metals to achieve a stable electron configuration by filling their outermost energy level, similar to noble gases.
