What are stable electron configurations?

Electron configurations can also predict stability. An atom is at its most stable (and therefore unreactive) when all its orbitals are full. The most stable configurations are the ones that have full energy levels. These configurations occur in the noble gases.

Which is the most stable electron configuration?

A full valence shell is the most stable electron configuration. Elements in other groups have partially filled valence shells and gain or lose electrons to achieve a stable electron configuration.

What is an example of a stable electron configuration?

According to the periodic table, some examples of stable electron configurations are: Neon {10 (2 + 8) electrons} Argon {18 (2 + 8 + 8)} Krypton {18 (2 + 8 + 8)}

What is meant by stable configuration?

(a) Stable electronic configuration means an atom in which the outermost (valence) shell is complete.

Which configuration is more stable?

The most stable electron configuration is that of a noble gas, due to the fact that its valence shell is filled. For helium, that means two valence electrons (a duet) in the 1s sublevel, and for the rest it means eight valence electrons (an octet) in the outermost s and p sublevels.

Which has more stable configuration?

1. Which Electron Configuration is the Most Stable? Ans. It is observed that the noble gases have the most stable orbital configuration.

Which is more stable configuration in?

It is observed that the noble gases have the most stable orbital configuration. The reason behind it is their valence shell is completely filled.

What is the most stable element and why?

The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.

Which of the following electron is more stable?

What is the difference between stable and unstable electron configuration?

Answer: An stable electronic configuration refer to an atom in which the outermost shell is complete. Whereas an unstable electronic configuration refers ta an atom in which the outermost shell is incomplete.

How do the atoms acquire stable configuration?

A stable electron configuration for the representative or main group elements is a noble gas configuration. Atoms of the representative elements achieve a noble gas configuration by gaining or losing electrons and becoming ions, or by sharing electrons.

Which is more stable configuration and why?

What makes atoms have a stable electron configuration?

Answer and explanation: Electron configuration is the distribution of electrons in an atom. In order for the electron configuration to be stable, an atom (o ther than Hydrogen and Helium) must have a full outer octet, or 8 electrons in it’s outermost shell .

What electron configuration do the noble gases have in common?

Noble gases have eight valence electrons, that is, they have eight electrons in their outermost orbit (except helium). Thus, they exhibit stable octet or duplet configuration. Hence, the elements of group 18 exhibit very high ionization enthalpies.

Which electron configuration represents a transition element?

The general electronic configuration of transition elements is (n-1)d 1-10ns 1-2. The (n-1) stands for inner shell and the d-orbitals may have one to ten electrons and the s-orbital of the outermost shell (n) may have one or two electrons.

Does lithium have a stable electron configuration?

A lithium atom has two electrons orbiting in an inner shell and only one electron orbiting in its outer shell. The outer shell is incomplete, and therefore unstable. Li atoms readily give up one electron to form positively charged, Li+ ions. These ions have the same stable electron configuration as the noble gas helium.
