Two or more elements combined chemically is a compound and the smallest unit is a molecule.
The smallest particle of a covalent compound that shows the properties of that compound is a molecule.
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.
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.
Molecule is the smallest particle that still holds the same 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.
Molecule is the smallest particle that still holds the same compound.
The smallest particle of a covalent compound that shows the properties of that compound is a molecule. In a covalent compound, atoms share electrons to form stable bonds, and the smallest unit that retains the chemical properties of the compound is the molecule, which consists of at least two atoms bonded together.
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.
The smallest particle of a covalent compound is a molecule, which consists of two or more atoms that are bonded together by sharing electrons.
A molecule is the smallest particle of a molecular compound.
Molecule is formed from two or more combined atoms.
