which atom in a water molecule has the greatest electronegativity?
Fluorine has the largest electronegativity value among all the elements.
helium
Electronegativity
Pauling defined electronegativity as the ability of an atom to attract electrons towards itself in a chemical bond. He developed a scale to quantify electronegativity values for elements based on their chemical properties. A higher electronegativity value indicates a greater ability of an atom to attract electrons in a bond.
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.
Fluorine has the greatest electronegativity among the options listed. Electronegativity is a measure of an atom's ability to attract shared electrons in a chemical bond, and fluorine has the highest electronegativity value on the Pauling scale.
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 tendency of an atom in a compound to attract electrons towards itself. It is a measure of an atom's ability to form bonds with other atoms by attracting shared electrons. Electronegativity values range from 0 to 4. Electronegativity increases from left to right across a period and decreases down a group on the periodic table.
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.
