2 Hydrogen ions and 1 Oxygen ion
Molecule I believe
Gold molecule is an element. A water molecule is a compund, H2O, composed of two elements
the answer is element
Water is not a chemical element; it is a compound made up of two elements: hydrogen and oxygen. The chemical formula for water is H2O, indicating that each water molecule contains two hydrogen atoms and one oxygen atom.
An "element" is made up of a single type of atom. Water is a combination of two elements (types of atoms), namely, hydrogen and oxygen.
Water is a pure compound -- all of it is one kind of molecule: H2O.
Water molecule (H2O) has 2 hydrogen atoms and 1 oxygen atom.
it tells you how much of the molecule the element is
The subscript to the right of an element tells you how many atoms of that particular element are in a molecule. For example, in the water molecule H2O, there are two hydrogen atoms and one oxygen atom.
This is a compound, a molecule.
False. Water is a molecule made of 2 parts hydrogen one part oxygen. NOT AN ELEMENT.
The atom of an element is smaller than a molecule.
