A molecule is the smallest part of an element or compound that can exist independently.
Molecules may be made up of atoms of the same element such as Hydrogen gas (H2 - two atoms of Hydrogen), or atoms of different elements such as Sodium Chloride (NaCl).
Substances made up of molecules consisting of atoms of different elements are called COMPOUNDS. (The word "compound" means made up of several parts.)
Some molecules are very large and may consist of hundreds, or even thousands of atoms.
The FORMULA of a substance is a way of describing the composition of the molecules of the substance. For example H2 means the smallest unit of Hydrogen gas consists of two atoms of Hydrogen combined together.
NaCl
means the smallest unit of Sodium Chloride consists of one atom of Sodium combined with one atom of Chlorine. It could be written as: Na1Cl1, but it is a convention that the "1s" are never written.
A molecule of Hydrochloric acid is made up of the elements Hydrogen and Chlorine - one atom of Hydrogen and one atom of Chlorine.
A molecule of water is made of the the elements Hydrogen and Oxygen - two atoms of Hydrogen combined with one atom of oxygen.
Sugar (C12H22O11) is made up of 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms.
Many elements in particular the gases occur naturally as molecules e.g.
H2, O2, N2, Cl2.
NOTE: Remember that a charged atom is called an "ion". It would be more correct to say that the smallest unit of Sodium Chloride consists of one ion of Sodium and one ion of Chlorine.
To work out the formula of a compound you need to know the valency of each of its ions ...
Valency is the number of electrons an atom tends to gain, lose or share in order to satisfy the Octet Rule.
What else can I help you with?
What m is made of two or more atoms joined together?
A molecule is made of two or more atoms joined together through chemical bonds. These atoms can be the same element or different elements, leading to the formation of various compounds.
What is two or more atoms?
Two or more atoms bonded together for a molecule or compound.
When compound called molecule?
A compound is made up of two or more different elements that are chemically bonded together. A molecule is the smallest unit of a compound that retains all the properties of that compound. In other words, all compounds are made up of molecules, but not all molecules are compounds.
What is the question of a molecule and a compound?
The question of a molecule is the arrangement of atoms that make up the molecule, including the types of atoms and how they are bonded together. A compound is a substance made up of two or more different types of atoms bonded together in a specific ratio.
When two or more atoms combine they create what?
Two or more atoms combine to form a molecule.
Are individual atoms compounds?
No. A molecule is made up of compunds, and a compound is made up of two or more atoms.
Is a molecule a compound?
Not necessarily. A molecule is the smallest unit of a compound that retains its chemical properties, but a compound is a substance made up of two or more different elements chemically bonded together. So, all compounds are molecules, but not all molecules are compounds.
What m is made of two or more atoms joined together?
A molecule is made of two or more atoms joined together through chemical bonds. These atoms can be the same element or different elements, leading to the formation of various compounds.
How do you know something is a compound?
A compound is a molecule made of two or more different compounds. Therefore, if there are two elements listed in the name of a substance, it is a compound.
Why compounds are molecules?
All compounds are made up of molecules. For example, salt, a compound, is composed of molecules (NaCl). By please do remember that molecules are not only limited to compounds. Meaning, there are also molecules that are not classified as compounds. The definition of a compound is a substance that is made up of two or more elements. A molecule is composed of two or more ATOMS connected by chemical forces. An example is oxygen air (O2). Oxygen air is a diatomic MOLECULE but it is NOT a COMPOUND.
What is two or more atoms?
Two or more atoms bonded together for a molecule or compound.
When compound called molecule?
A compound is made up of two or more different elements that are chemically bonded together. A molecule is the smallest unit of a compound that retains all the properties of that compound. In other words, all compounds are made up of molecules, but not all molecules are compounds.
Where are elements and compounds usually found?
In literally every single thing in the universe. Elements are the very building blocks of things. Compounds are things that are made up of more than two elements. If something is made up of two Oxygen molecules, it is not a compound. If something is made up of an Oxygen molecule, and a Carbon molecule, it would be a compound.
What are all compounds made of?
All compounds are made of two or more atoms.
What is the main difference between a molecule and compound?
A molecule is formed when two or more atoms join together chemically. A compound is a molecule that contains at least two different elements. All compounds are molecules but not all molecules are compounds.
What is the question of a molecule and a compound?
The question of a molecule is the arrangement of atoms that make up the molecule, including the types of atoms and how they are bonded together. A compound is a substance made up of two or more different types of atoms bonded together in a specific ratio.
Can compounds be made up of many molecules?
Yes, compounds are made up of two or more different types of atoms that are chemically bonded together. Each molecule within a compound consists of specific ratios and arrangements of these atoms. Therefore, compounds can indeed be made up of many molecules.
