Question

How many different elements are in ammonium hydroxide (nh4oh)?

Answer 1

the different  element that are  in  ammonium  hydroxide (NH4OH)   are   three(3)

that  is  nitrogen (N)
              Hydrogen (H)
              oxygen (O)
to  make a  total of three  atoms
 nitrogen,  hydrogen   and  oxygen   made  up  ammonium  hydroxide  that  is  1 atom of  nitrogen   5  atoms of  hydrogen    and  1 atom of oxygen.

Answer 2

Answer: There are 3 different types of elements in the given compound.

Explanation:

Elements are defined as the smallest unit which cannot be further divided. These have same types of atoms. For Example: Carbon (C), Hydrogen (H), etc..

For a given chemical compound $NH_4OH$

There are 3 different kinds of elements which are nitrogen (N), hydrogen (H) and oxygen (O).

In 1 mole of ammonium hydroxide, 1 mole of nitrogen atoms, 5 moles of hydrogen atoms and 1 mole of oxygen atom is present.

Thus, there are 3 different types of elements in the given compound.
