H2O two Hydrogen atomss and One Oxygen atom
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.
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 compounds make up elements. Elements make up compounds, so there are no compounds in cadmium since it is an element.
No, tap water is not an element. It is a compound made up of two elements, hydrogen and oxygen.
No. Water is not an element it consists of molecules made from hydrogen and oxygen
No. An element is made up of only one type of atom. Water and oil are made up of many different types of atoms, so they do not form an element.
No. An element is made up of only one type of atom. Water and oil are made up of many different types of atoms, so they do not form an element.
Contemporary science does not consider water to be an element.
