The octet rule is a chemical rule of thumb that reflects observation that atoms of main group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electron configuration as a noble gas. The rule is especially applicable to carbon , nitrogen , oxygen , and the halogens, but also to metals such as sodium or magnesium.
The octet rule states that atoms present in the chemical compounds have noble gas electronic configuration. Thus, option A is correct.
The atom has been smallest unit of matter that has been consist of the protons, electrons, and neutrons. Electrons are the revolving bodies, and have been present outside the nucleus.
The availability of electrons in the valence shell has been determining the reactivity of the compound to form the molecule.
The molecules react with each other to complete their octet, and attain the stable configuration. The stable configuration has been representation of the noble has configuration as well.
Thus, the octet rule states that, in chemical compounds, atoms tends to have noble gas electronic configuration. Thus, option A is correct.
