The electronegativity is 2.1 for H and 3.0 for N. Based on these electronegativities, NH4 would be expected to The electronegativity is 2.1 for H and 3.0 for N. Based on these electronegativities, NH4 would be expected to have polar covalent bonds with a partial positive charges on the H atoms. be ionic and contain H - ions. have polar covalent bonds with a partial negative charges on the H atoms. be ionic and contain H ions.

Electronegativity difference of N and H is: 0.9

Its covalent

Electronegativity difference of F and CI is: 1.0

Its covalent

First statement is true:

NH₄ would be expected to have polar covalent bonds with a partial positive charges on the H atoms.

Explanation:

Nitrogen (N) and hydrogen (H) are two nonmetals; thus, it should be a hint to assert that they form a covalent bond.

The difference in electronegativities between N and H is 3.0 - 2.1 = 0.9.

That makes that the bonds be polar. Ions are not formed because to transfer the electrons from one atom to the other (to form ionic bonds) requires an electronegativity difference greater than about 1.7.

Since N is more electronegative than H, in the molecule NH₄, each N atom will pull the electron density toward itself acquiring a partial negative charge and leaving H atoms with a partial positive charge.

Thus, each NH bond is polar covalent with a partial positive charge on the H atoms (first statement from the choices).
