For metals high electronegativity mean low reactivity; for halogens, C, O, N, S, etc. the meaning is high reactivity.
electronegativity
The tendency of an atom to attract electrons is called electronegativity. It is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
It is more likely to attract electrons. :)
The term which means the amount that a given atom (or radical) attracts electrons is electronegativity.
The electronegativity of oxygen (O) is 3.44 on the Pauling scale. Electronegativity is a measure of an atom's ability to attract shared electrons in a chemical bond towards itself. Oxygen has a relatively high electronegativity due to its strong affinity for electrons.

an atom with a high electronegativity, like fluorine

the tendency of the atom to pull on electrons Apex : )
which atom in a water molecule has the greatest electronegativity?
The term which means the amount that a given atom (or radical) attracts electrons is electronegativity.
The electronegativity difference between hydrogen and sodium atoms is approximately 2.1. This means that hydrogen atom is more electronegative compared to sodium atom. Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
Electronegativity is tendency of an atom to attract shared pair of electrons towards itself in a chemical bond. Since it is only relative electron tendency, it has no specific units. Electronegativity is elated to: (a) Size of an atom. (b) Effective nuclear charge Atom with small size and high nuclear charge has high electronegativity due to the strong pull exerted on shared electrons by the nucleus. For example, fluorine is highly electronegative element with electro negativity value 3.92 due to small size and high effective nuclear charge. Atom with greater size and less nuclear charge has low electronegativity as its nucleus does not exert a stong attractive force on shared electrons. For example, Caesium is least electronegative element with electronegativity value 0.7 due to its big sizes and less effetive nuclear charge.
