Elements are the simplest type of chemical. An element is composed of atoms. Atoms in turn are composed of subatomic particles. However, all substances are composed of atoms, and there are no substances composed only of subatomic particles - at least, not on Earth. It is believed that there exist neutron stars composed only of neutrons. In that situation, you could say that the neutron is the smallest type of substance.
The smallest part of a substance that still has the characteristics of that substance is called a molecule.
No. Elements are made up of smaller elements called atoms.
The simplest substance in chemistry is the element, because elements cannot be broken down, only changed. Of the elements, the smallest and simplest is hydrogen.
Elements and compounds
Yes, chemical elements are substances.
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.
Elements.
A single hydrogen atom.
An atom is the smallest particle of a substance.
An atom is the smallest particle of a substance.
The smallest representative unit of a substance is called a molecule. The number and type of atoms present in a molecule are determined by the chemical formula of the substance. The chemical formula provides information on the number and type of each element present in the molecule.
Elements are made of atoms. The atom is the smallest single unit that exists in any type of element and their number varies in the elements.
