What is the oxidation number for each atom in nh4cl?

a.

n=+3, h=-4,cl=+1

b.

n=+3, h=+1,cl=-1

c.

n=-3, h=-1,cl=+1

d.

n=-3, h=+1,cl=-1

Answer is: D. N=-3, H=+1, Cl=-1.

Ammonium chloride (NH₄Cl) is chemical compound with neutral charge.

1) Hydrogen (H) has oxidation number +1 in compounds with nonmetals (nitrogen and chlorine).

2) Chlorine has oxidation number -1, because ammonium ion (NH₄⁺) has positive charge.

3) In ammonium cation (NH₄⁺), nitrogen has higher electronegativity than hydrogen, so it has negative oxidation number -3:

x + 4 · (+1) = +1.

x = 1 - 4.

x = -3; oxidation number of nitrogen.

Electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.
