Elements are the simplest building blocks you can break matter down into using purely chemical methods. They are a pure substance made up from only one type of atom.
When you mix elements together these form compounds. The important difference is that as they are a mixture of more than one type of element, they CAN be broken down into more simple substances using chemical means!
As such Hydrogen or Oxygen cannot be simplified chemically (they are therefore elements), however dihydrogen monoxide (H2O or water!) is a mixture of these elements that can be broken down using chemical means and so is a compound...
Hydrogen and oxygen are both elements. When they combine to form water (H2O), then it becomes a compound.
Hydrogen and oxygen together form a compound called water, which is a chemical substance composed of two different elements. Hydrogen and oxygen on their own are elements.
Water is a compound made of hydrogen and oxygen. Nitrogen and oxygen are elements on their own.
There are 3 elements in the compound C6H12O6: carbon (C), hydrogen (H), and oxygen (O).
Water is a compound of the elements oxygen and hydrogen.
Hydrogen and oxygen are the reactants and water is the product.

Four, actually; the "CHON" elements of Carbon, Hydrogen, Oxygen and Nitrogen.
Water is a compound made of hydrogen and oxygen. Nitrogen and oxygen are elements on their own.
No. Hydrogen and oxygen are elements, not compounds. They are not the same.
Nitrogen, yes. Water, no. Water is a compound of the elements oxygen and hydrogen.
There are 3 elements in the compound C6H12O6: carbon (C), hydrogen (H), and oxygen (O).
It is a compound of Hydrogen and oxygen elements
No, Water is a compound of Hydrogen and Oxygen, which are elements, but when reacted together: 2H2 + O2 = H20
carbon hydrogen oxygen
