Answer:
1 atom of sodium, 1 atom of oxygen and 1 atom of hydrogen
Explanation:
- An atom is the smallest particle of an element that can take part in a chemical reaction.
- Compounds and elements are made of atoms.
- Atoms of the same element are similar while atoms making a compound are different as they are from different elements.
- For example, Cl₂ is an element made up of two chlorine atoms, while NaOH is a compound made up of atoms of different elements. That is, one sodium atom, one oxygen atom and one hydrogen atom.
