From which atoms does oxygen can be made?
Oxygen is made up of It is replenished by plants and other photosynthetic organisms. Oxygen also makes up most of Earth's oceans by mass. A water molecule (H2O) is made up of two hydrogen atoms and one oxygen atom. Although there are more hydrogen atoms in water, hydrogen has less mass.
What is the unit that makes up matter?
atoms
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
