    Is N3H a covalent bond? Explain why?

    I believe the formula is NH3, not N3H.

    This is ammonia.

    To determine the type of bond, you need to know the electronegativity of the 2 elements.

    N = 3.0, H = 2.1

    The formula from my chemistry book:

    % Ionic character = 100% * (Large E.N – Small EN) ÷ (Large EN)

    If % Ionic character is greater than 50%, the bond is ionic.

    If % Ionic character is between 5% and 50%, the bond is polar covalent.

    If % Ionic character is less than 5%, the bond is nonpolar.

    100 * (3.0 – 2.1) ÷ 3.0 = 30%

    Each of the 3 N – H bonds is polar covalent. The shape of the NH3 molecule is pyramidal, with the nitrogen atom at the top and the 3 H’s as the base. The molecule is polar, because top, N, has a partial negative charge and the base with 3 H’s has a partial positive charge.

    see the shape at the web site below.

    In an ionic bond, the atoms are certain mutually via the appeal between oppositely-charged ions. as an occasion, sodium and chloride type an ionic bond, to make NaCl, or table salt. In a covalent bond, the atoms are certain via shared electrons. If the electron is shared the two between the atoms forming a covalent bond, then the bond is asserted to be nonpolar. regularly, an electron is greater attracted to a minimum of one atom than to a various, forming a polar covalent bond.

    Yes. For one thing, covalent bonds usually occur between nonmetal atoms. Secondly, the electronegativity difference between the two elements should be lower than a certain number.
