What evidence is there that an electron octet is a particularly stable valence configuration?

The evidence comes from the Noble Gases of the Periodic Table of the Elements. Electron octet rule for stability is based on the noble gases, which are also called the inert gases because they are so stable they rarely react with anything. Chemists have come up with the theory of electron orbitals to explain stability. These are referred to as S orbital, P orbital, D orbital, etc. When the outer most orbital contains an octet the electron orbital resembles the Noble Gases and hence why it is considered stable valence configuration.

The outer shell of neon is full, 2s2, 2p6
The outer shells of the rest of the noble gases are not full but all have ns2, np6 outer shells, the octet.

∙ 13y agoNoble gas configurations are stable because their outermost energy level is completely filled up. This means that they don't normally react with other elements.

What is the element with a valence electron configuration of 2s2?
Beryllium would have that configuration
How many valence electrons does an atom of potassium have?
4
How many valence electrons does the element cesium have?
A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
How many valence electrons does a chlorine atom have if its electron configuration is Ne3s23p5?
With an e- configuration of [Ne] 3s23p5, the atom will be found in Group VII A, meaning that there are 7 valence electrons.
Electron configuration for francium?
7s1 because the definition of valence electrons are the outermost s and p electrons therefore in this case there is only an outermost s electron and therefore the answer is 7s1. NOTE:IT DOES NOT INCLUDE THE D AND THE F ELECTRONS!!!!Other valence configuration examples include;Nitrogen : 2s2 2p3Chlorine : 3s2 2p5Zinc: 4s2Bromine: 4s2 4p5
What is the valence electron configuration for the phosphorus atom?
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
What is the valence configuration for krypton?
Krypton has 8 valence electrons.The electron configuration is: [Ar]3d10.4s2.4p6.
What element has the same valence electron configuration as phosphorus?
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
What is the name of the element with a valence electron configuration of 3s23p3?
The electron configuration of phosphorus is [Ne]3s2.3p3.
What is the valence electron configuration for the magnesium atom?
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.

How many valance electrons are there in Fr plus?
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
