A particle diagram representing a mixture of an element and a compound would show individual atoms or molecules of the element and compound mixed together without forming any new chemical bonds. The particles of the element and compound would be distinct from each other within the mixture.
A molecule is the smallest particle of a "compound" being that compounds are made up of more than one atom. The smallest particle of any "chemical element" that retains its properties would be the atom.
If the chemical formula contains only one element (such as Mg, K or Cl2) it would be an element. If it contains two or more elements (such as NaCl, CO2 or CuSO4.5H2O) then it would be a compound.
No, HNO3 is not an element. It is a compound. HNO3 represents nitric acid, which is made up of atoms of hydrogen, nitrogen, and oxygen.
The chemical symbol of an element represents a compound. A compound is made up of two or more different elements chemically bonded together. The chemical symbol for each element in the compound is used to represent its composition.
Subscripts in a compound are used to indicate the number of atoms present for each element in the compound. They show the ratio at which the elements are combined to form the compound. Each subscript number represents the number of atoms of the element that follows it.
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.
An element is a part of a compound.
An element.

It is a compound. It represents a chemical reaction, which makes it a compound.
A molecule is the smallest part of a compound that still retains the properties of said compound. As the atom is the smallest particle of an element into which it can be divided and still retain all the properties of that element, the molecule is the atom's analog for a compound.
A molecule is the smallest particle of a "compound" being that compounds are made up of more than one atom. The smallest particle of any "chemical element" that retains its properties would be the atom.

This is the atom of a chemical element.
If the chemical formula contains only one element (such as Mg, K or Cl2) it would be an element. If it contains two or more elements (such as NaCl, CO2 or CuSO4.5H2O) then it would be a compound.
To understand, you first need to understand the difference between an element and a compound. An element is any element from the Periodic table. For example, oxygen. A compound is a substance in which more than one element are bonded chemically. This is not to be confused with a mixture, which is simple a mixture of substances with no chemical bonding. An example of a compound would be water, consisting of hydrogen and oxygen bonded together.Now that we've established to difference between an element and a compound, we can explore what the smallest particle of each is. The "smallest particle" is the smallest you can go while still keeping the properties of the original substance.The smallest particle of an element would be an atom. But when dealing with compounds, if you break them down to atoms, then those atoms don't have the same properties as a compound. The smallest particle of a compound is a molecule. In our example of water, a water molecule consists of two hydrogen atoms and one oxygen atom, chemically bonded together. The molecule, consisting of three atoms, has the chemical properties of water. But if you break it down so you just have an oxygen atom and two hydrogen atoms, none of them would have the properties of the original compound (water).Thus, the smallest particle of an element is an atom, and the smallest particle of a compound is a molecule. The difference between the two is that an atom is an atom, and a molecule is two or more atoms chemically bonded.
The smallest particle of a compound that can exist and still retain the characteristic properties of that substance is a molecule. For gaseous elements, individual atoms are the smallest particle that retains the characteristic properties of the element.
