Question

which of the following does not apply to electronegativity? check all that do not apply. 1) electronegativity is the relative ability of an atom/element in a molecule/compound to attract the shared pair of electrons towards itself 2) a nonmetal with a higher electronegativity will from a polar covalent bond with another nonmetal of lower electronegativity 3) electronegativity decreases across a period and increases down a group 4) h - o bond is less polar than h - c bond

Explanation:

1. This is the correct definition of electronegativity.
2. A higher - electronegativity non - metal forms a polar covalent bond with a lower - electronegativity non - metal due to unequal sharing of electrons.
3. Electronegativity increases across a period and decreases down a group, so this statement is incorrect.
4. Oxygen is more electronegative than carbon, so the H - O bond is more polar than the H - C bond, and this statement is incorrect.

Answer:

1. Electronegativity decreases across a Period and increases down a Group
2. H - O bond is less polar than H - C bond
