What is composed of more than one atom?

A molecule, however, is composed of more than one atom. Some elements exist naturally as molecules. For example, hydrogen and oxygen exist as two-atom molecules.

What is a group of atoms called?

When atoms join together, the group is called a molecule.

What is composed of more than one element?

A compound is a chemical substance made up of two or more elements.

What compounds is composed of more than two atoms?

As the name suggests, a polyatomic ion is a charged entity composed of several atoms bound together. Polyatomic ions have special names that are used in the nomenclature of the compounds containing them.

What is two or more atoms joined together?

A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together.

What is it called when two atoms combine?

When atoms combine by forming covalent bonds, the resulting collection of atoms is called a molecule. We can therefore say that a molecule is the simplest unit of a covalent compound.

What are two atoms joined together called?

Either way, the atoms become bonded chemically to form a molecule. When an atom donates an electron to the other, both atoms become ions, each with an opposite charge, and they are bonded by electrostatic attraction. This is called an ionic bond.

What compose an element?

An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron. If you change the number of protons an atom has, you change the type of element it is.

What are compound molecules?

Molecules of compounds have atoms of two or more different elements. For example, water (H2O) has three atoms, two hydrogen (H) atoms and one oxygen (O) atom. Methane (CH4), a common greenhouse gas, has five atoms, one of carbon (C) and four of hydrogen (H, see Fig.

Are molecules composed of 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.

What are two compounds?

Water, carbon dioxide and table salt are some examples of compounds.

What is formed when one or more than one atom bonds to another atom?

Ionic Bonds formed when one or more electrons are transferred from one atom to another. Covalent bonds are shared by atoms moving electrons actually travel around the Nuclei of both atoms forming Covalent Bonds.
