The smallest particle of an element that cannot be divided or broken up by chemical means. It consists of a central core (or nucleus), containing protons and neutrons, with electrons revolving in orbits in the region surrounding the nucleus.
What is the smallest particle in a chemical element or compound that is made up of two or more atoms?
molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
Is electron the smallest particle?
Quarks are the smallest particles we know . Many quarks make up one electron, proton and neutron. But if we refer to chemistry electron is the smaller both than proton and neutron.
What is the smallest particle of an element that takes part in a chemical reaction?
According to the Daltons theory, the smallest particle of an element that can take part in a chemical reaction is an atom.
Why is the smallest particle in a compound a molecule?
The molecule can be defined as the smallest particle of a compound that is capable of independent existence. The molecule is an electrically neutral group of two or more atoms chemically bonded together. Atom is the smallest particle of matter, thus a combination of atoms is called molecule.
Is molecule the smallest particle of a compound?
The smallest particle of most compounds in living things is called a molecule. Consider water as an example. A molecule of water always contains one atom of oxygen and two atoms of hydrogen.
Is the smallest particle of molecule?
A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms.
What are the smallest compound?
The smallest unit of a compound is called a molecule.
