What elements (besides carbon, hydrogen, and oxygen) are in an apple?

Question

I also believe that there is iron and copper, but I am sure that there are more!

Answer 1

That question's a little "loose". An apple is a natural product and any given apply might have almost any element in it, in trace quantities. Whatever is in the soil may be picked up by the tree. Any actual apple you buy in a supermarket is likely to have been sprayed with pesticides and wax, so may contain all sorts of stray molecules.

Apples are comprised overwhelmingly of carbohydrates; there will be some nitrogen, too. Any other elements will occur only in trace quantities. It's up to you to decide which are significant.

I see a study of mineral content of Fuji apples by Iwane of Morioka Junior College of Iwate Prefectural University; studied were sodium, potassium, magnesium, calcium, iron, manganese, copper, zinc, and phosphorus.

Answer 2

Don't forget Uranium,Potassium,Iodine,Calcium,Strontium and what ever the aple tree roots absorb and what ever is in the rain water that falls on it. Like diluted Sulphuric acid. So,Sulphur would definately be in it.

Answer 3

nitrogen (in protein)
phosphorus (in phospholipid)
sulphur (in some amino acids)
