Question

is 8o is electronegative substance?

Answer 1

yes it is electronegative

Answer 2

Oxygen(8) is the second most electronegative element of periodic table after flourine(F).

Electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons (or electron density) towards itself.



An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it.


What makes oxygen electronegative is its valence shell. Oxygen has 6 valence electrons so it can still attract 2 more electrons to fill the valence shell. If a certain element has empty valence shell, then its electronegativity lowers. The more electrons gained, the more reactive an element is.This is what happens to oxygen.

Oxygen does not only contain 8 electrons but also 8 protons. The protons are also responsible in pulling electrons to the nucleus. Due to the 8 protons the oxygen has, more electrons are pulled making oxygen electronegative.
