What elements have stable electron configurations?
Group 18 elements (helium, neon, and argon are shown in Figure 2) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration.
What is an example of a stable electron configuration?
According to the periodic table, some examples of stable electron configurations are: Helium. Neon {10 (2 + 8) electrons} Argon {18 (2 + 8 + 8)}
What is a stable element configuration?
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. The noble gases are very stable elements that do not react easily with any other elements.
Which of the following groups contain 3 elements with stable electron configurations?
Stable Electron Configuration: All of the elements in group 18, also known as the noble gases, have stable electron configuration because they reach the maximum number of electrons in their shells.
Which configuration is more stable?
1. Which Electron Configuration is the Most Stable? It is observed that the noble gases have the most stable orbital configuration.
What elements have unstable electron shells?
Therefore the vast majority of the elements in the periodic table have unstable electron configurations.
- Hydrogen. Hydrogen is the simplest element in the periodic table and consists of a single proton and a single electron.
- Sodium.
- Carbon.
- Chlorine.
Is sodium stable or unstable?
This is a very unstable arrangement, and the element sodium is a highly reactive, deadly white semi-solid that will burst into flames on exposure to the air or will burn through human flesh on contact. A reactive substance. Chlorine atoms have 17 electrons.
What is stable electron?
Stable configuration They have two or eight electrons in their valence shell. They do not gain, lose or share electrons.
Which is the most stable configuration?
The most stable electron configuration is that of a noble gas, due to the fact that its valence shell is filled.
