which atom in a water molecule has the greatest electronegativity?
helium
One atom is a metal and one is a nonmetal One atom has a high electronegativity value, while the other value is relatively low.
Electronegativity is the ability of an atom to attract towards it the electron pair of a covalent bond. An atom with low electronegativity is poor at doing this. For instance, the electronegativity of bromine is less than that of chlorine.
Electronegativity is the relative tendency of atoms to attract electrons in bond. The electronegativity is affected by both the atomic number and the distance from the core of the valence electrons.
Electronegativity of hydrogen is 2,20. Electronegativity of sodium is 0,93.
Fluorine (F): 4.0 Oxygen (O): 3.5 Nitrogen (N) and Chlorine (Cl): 3.0
One atom is a metal and one is a nonmetal One atom has a high electronegativity value, while the other value is relatively low.
Atoms with the lowest electronegativity values located on the leftmost part of the Periodic Table. The atom with the lowest electronegativity belongs to Francium.

Electronegativity is the ability of an atom to attract towards it the electron pair of a covalent bond. An atom with low electronegativity is poor at doing this. For instance, the electronegativity of bromine is less than that of chlorine.
The term which means the amount that a given atom (or radical) attracts electrons is electronegativity.
Electronegativity is the relative tendency of atoms to attract electrons in bond. The electronegativity is affected by both the atomic number and the distance from the core of the valence electrons.
Linus Pauling defined electronegativity as "the ability of an atom in a molecule to attract electrons to itself."
Electronegativity of hydrogen is 2,20. Electronegativity of sodium is 0,93.

Electronegativity
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.
