An element is the correct answer
an element
Infact it is not an element but rather a molecule..
A substance composed of two or more atoms of the same element is just a pure substance/element, a substance composed of different atoms is called a compound
If the substance is an element, the smallest will be an atom. If it is a compound, then that would be a molecule.
It would be a molecule. It cannot be considered a compound because it contains atoms of only one element.
an element

The smallest part of a substance is a molecule. A molecule can be a compound of different elements or be comprised of a single element.
A substance composed of two or more atoms of the same element is just a pure substance/element, a substance composed of different atoms is called a compound
If the substance is an element, the smallest will be an atom. If it is a compound, then that would be a molecule.
It would be a molecule. It cannot be considered a compound because it contains atoms of only one element.
If it is an element, then the smallest particle that retains the characteristics of the element is an atom. If it is a diatomic element, then the smallest particle that retains the characteristics of the element is a molecule. If it is a molecular compound, then the smallest particle that retains the characteristics of the compound is a molecule. If it is an ionic compound, the smallest particle that retains characteristics of the compound is a formula unit.
A molecule is an element if it contains only one kind of atom, like oxygen, O2, and chlorine, Cl2. A molecule is a compound if it contains more than one kind of atom, such as water H2O, or methane, CH4.
A single molecule of hydrogen is the smallest substance. It consists of jut two protons and two electrons.
O3 is a molecule / compound, not element
The smallest part of any chemical element that can exist is an atom of that element. The smallest part of a chemical compound that can exist is a molecule of that compound.
No, it contains many compounds and elements mixed in any ratio. It contains humus, and other particles including dirt. It is a mixture. A pure substance must contains only one type or atom (Element) or one type of molecule (compound).
