molecule
atom - smallest piece of an element that keeps its chemical properties; compound - substance that can be broken into elements by chemical reactions
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 piece of matter a compound can be broken into and still have the same properties is a molecule. When a compound is broken down into individual molecules, the chemical properties of the compound remain unchanged because the molecules contain the same types and numbers of atoms that give the compound its characteristic properties.
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.
An Atom.
The smallest piece of an element that still retains the properties of the element is an atom. Atoms are the building blocks of all matter and preserve the unique characteristics of each element, such as its chemical behavior and physical properties.
The smallest piece of an ionic compound is called an ion, which is a charged particle formed when atoms gain or lose electrons. These ions are brought together through electrostatic forces to form a neutral ionic compound.
An atom is the smallest piece of matter that retains the properties of an element. It consists of a nucleus (protons and neutrons) surrounded by electrons. Each element has its own unique type of atom.
The smallest magnification lens on a compound light microscope is the scanning objective lens, typically with a magnification of 4x.
A single atom of gold is the smallest piece of gold that can still be considered gold. Gold is a chemical element, and even in its smallest form, it retains the properties that define it as gold.
If the substance can conduct electricity in solution, create ions when dissolved in water, and form crystals with a regular repeating pattern, it suggests that the substance is an ionic compound. Additionally, if the substance has high melting and boiling points, this is another indication of ionic bonding.
An atom is the smallest piece of an elemental chemical, a molecule is the smallest piece of a compound chemical (composed of several elements). However due to quantum effects, neither an atom nor a molecule has the properties that we associate with that specific chemical. You need a minimum of several hundred or thousand atoms or molecules in most cases for the "bulk" chemical properties to begin to appear.
