When two or more atoms bond together, they are called molecules. Examples include water (H2O - two atoms of hydrogen and one of water), carbon dioxide (C02 - one atom of carbon and two atoms of oxygen)
the smallest particle of a substance; molecules are made up of one or more atoms. (Back to "Warning, the rays of the sun can be dangerous") (Back to "The Hole in the Ozone Layer")
the smallest single components of all living things that make up the structure of cells and tissues and perform all the life processes of the cells and the body.
Molecules are aggregates of one or more atoms.
the simplest unit of a chemical substance. Usually a group of two or more atoms
atoms chemically bound together.
in chemistry, a group of various kinds of atoms held together by chemical bonding.
the smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms What is an Ecosystem
a tiny particle of matter
the smallest physical units of a substance that still retain the chemical properties of that chemical substance; molecules are the building blocks of a cell. Some examples are proteins, fats, carbohydrates, and nucleic acids.
an entity of two or more atoms.
Is the smallest building block of a compound that contains all the properties.
Units of two or more atoms held together by chemical bonds. The combination of atoms by chemical bonds with the component atoms in definite porportions, such as water (two H to one O).
The smallest particle of an element or compound that normally exists on its own and still retains its properties. Molecules normally consist of two or more atoms bonded together. Some molecules have thousands of atoms. Ionic compounds consist of ions and do not have molecules.
A group of atoms held together by chemical forces.
Small particles that make up matter, held together by God.
extremely tiny particles of which all materials are made .
are particles consisting of two or more atoms held together by chemical bonds; the smallest unit of a compound that displays the properties of that compound.
Atoms consist of a single nucleus surrounded by a cloud of electrons. Atoms are the fundamental building blocks of molecules. A molecule is any group of atoms that are bonded together and act as a unit. For example a water molecule contains two atoms of hydrogen and one of oxygen (H2O). Hydrogen and oxygen do not always bond to form water. Two atoms of hydrogen and two atoms of oxygen can bond to form hydrogen peroxide. While the periodic table has about 100 different chemical elements, these can combine in different ways to form tens of millions of different molecules.
Molecules is a journal of synthetic chemistry and natural product chemistry (ISSN 1420-3049). It started publication in 1996 and is a partly open access publication.
