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.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
