Can you have a molecule with only one element?

Can you have a molecule with only one element?

Not all molecules are compounds, since some molecules, such as oxygen gas (above image of molecule of-O2) or ozone (O3), consist only of one element or type of atom. Water is also a molecule because it is made from atoms that have been chemically combined.

Can a molecule be two different elements?

A molecule may consist of nonmetallic atoms of a single chemical element, as with oxygen (O2), or of different elements, as with water (H2O). The geometry and composition of a molecule will determine its chemical and physical properties. Isomers are molecules with the same atoms in different geometric arrangements.

What is made of only one element?

Answer: A pure substance is something that occurs in nature. An element is made up of one type of atom only and cannot be split further. A compound has the combined properties of the elements from which it is made.

Can an element be a molecule?

Some elements exist naturally as molecules. For example, hydrogen and oxygen exist as two-atom molecules. Other elements also exist naturally as diatomic molecules—a molecule with only two atoms (Table 5.4.

Are molecules only made of atoms?

Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Atoms that share electrons in a chemical bond have covalent bonds.

Can a molecule consist of just one atom?

A molecule may be homonuclear, that is, it consists of atoms of one chemical element, as with two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (two hydrogen atoms and one oxygen atom; H2O).

Does a molecule have more than one atom?

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 a compound made up of only one type of atom?

By definition a compound is composed of two or more different elements chemically bonded, which is same as saying more than one kind of atom. Examples of molecules that are not compounds but contain more than one atom, each of which is the same kind of atom.

What does it mean if the sample is made up of only one substance or more than one substances?

mixture
A mixture is a material system made up of two or more different substances, which are mixed but not combined chemically. A mixture refers to the physical combination of two or more substances in which the identities of the individual substances are retained.

Do molecules make up atoms?

When two or more atoms link up, they create a molecule . A molecule of water is made of two atoms of hydrogen (H) and one atom of oxygen (O). The molecular mass is the sum of the masses of all the atoms in the molecule. A collection of molecules is called a compound.

Can a molecule make an element an element?

Yes, Molecules are what create elements. two oxygen molecules and one hydrogen molecule creates a water(element) Answer 2 An element consists of only one sort of atom, but in some elements these atoms join together to form molecules, but these molecules will only be made of one type of atom.

Can a molecule have only one type of atom?

However molecules can have only one type of atom. The simplest are molecular elemental gasses such as , , , etc… But there are more complex ones. Like , i.e. Fullerene, a soccer-ball shaped atom with only carbon atoms: There are also other fullerenes with more carbon atoms (like ) which look like misshapen soccer balls.

Which is the simplest form of matter, an element or molecule?

(i) An element is the simplest form of matter which is made up of one kind of atoms. (ii) Different elements are made up of different kinds of atoms. (iii) An element may exist as an individual atom (e.g. argon, helium etc.) or as a molecule made up of the same two or more atoms which are chemically combined (e.g. most of the non-metals).

Can a cell be made from an element?

No, molecules are made from atoms of elements electrically bonded together.Cells are living structures made from millions of molecules.Atom -> Molecule -> Cell (contains billions of molecules) How are elements atoms molecules chemical bonds compounds mixtures and substances related?
