Answer is: D. sodium and sulfur.
When the electronegativity difference is greater, the bond polarity is increasing..
Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.
Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.
Δχ(Na-S) = 2.6 - 0.95 = 1.655; electronegativity difference between sodium and sulfur.
Ionic bond is the electrostatic attraction between oppositely charged ions (cations and anions).
Sodium is metal (forms cation) and sulfur is nonmetal (forms anion).
Answer:
Liquid
Explanation:
Gas is too far away, solid is close but it is not in a random pattern
Covelant bonds form when 2 atoms do not have full outer shells.
Both of the 2 atoms then join together and share their electrons in order to gain stability have have a full outer shell
They are on the left side of the equation.
