H2O two Hydrogen atomss and One Oxygen atom
Iron is made up of one type of particle which is why it is an element, whereas water is made up of two different particles so it is not an element.
No, tap water is not an element. It is a compound made up of two elements, hydrogen and oxygen.
-- Hydrogen -- Oxygen
water
A compound is not lighter than an element, if that element is part of the compound. Some compounds, like H2O would be lighter than, say, the element lead, but it is not lighter than the elements that make it up, i.e. hydgrogen and/or oxygen.
air, water, wind and earth
According to the modern definition of "element", water is made up of two different elements: hydrogen, and oxygen.

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.
