The valence/outer shell has to be completely full to be completely stable.
Argon does not have an electric configuration.
They achieve stable configuration by sharing their electrons in their outermost shell.
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
The stable configuration is when an atom has a full outer shell.
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
False
stable electronic configuration
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.
Oxygen atoms need to share or gain two electrons in order to achieve a stable electron configuration.
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
By acquiring noble gas configuration elements become stable .
