Made up of only 1 type of atoms. Made up of more than 1 type of atoms combined in a fixed ratio. Cannot be split into 2 or more simpler substances by physical or chemical reactions. Can be split into simpler substances constituent atoms by chemical reactions.
There are elements known to us. There is no limit to number of compounds that can be formed. A good example of this is hydrogen as in water. The term is also used for chemical substances in their pure form made up of a single element such as hydrogen gas. Out of the 94 elements that occur naturally and have atomic numbers ranging from 1 to 82, each one of them has a minimum of one stable isotope.
However, exceptions to this rule include technetium or element 43 and promethium or element Both of these elements do not have any stable isotopes. You need to know that there has been no radioactive decay recorded or observed for stable isotopes.
When you talk about a chemical compound, it refers to any type of substance that consists of a minimum of 2 different varieties of atoms or chemical elements that are fixed in a stoichiometric proportion and can also be termed as a chemical compound.
In case of any non-stoichiometric compound, the proportions can be reproducible without much trouble with regards to their specific preparations. You need to know that chemical compounds tend to possess a definite and one-of-a-kind chemical structure that is bound in a definite spatial arrangement with the help of chemical bonds.
For example, molecular compounds held by covalent bonds, intermetallic compounds held by metallic bonds, salts held by ionic bonds, and chemical complexes held by coordinate covalent bonds.
Once you have a clear idea about the definition of an element and a compound, it will be very simple for you to differentiate the two. Elements are made of a single type of atom, whereas, compounds are made up of several different atoms. You may say that compounds comprise of different elements. It is also very simple to break down compounds. But trying to break down an element is useless. These are some specific types of chemical compounds and they are:. Molecular compounds with the covalent bond.
Intermolecular compounds with the metallic bond. Salts with the ionic bond. Complex compounds with coordinate covalent bonds. Now, we are going to discuss the difference between compound and element in detail. Elements are pure materials containing one type of atom. Compounds include more than one kind of atom. Elements are classified depending on their properties, and compounds are ranked based on their bond type. Symbols represent elements, and compounds are defined by their chemical formulas.
Their atomic number identifies elements. Their atomic ratio separates compounds. Chemical reactions cannot break down elements, but they can break down the compounds. This is the main difference between compound and element. Some other factors differentiate between element and compound, such as total numbers, properties, composition, examples, etc.
The periodic table includes elements. The compounds are uncountable. The elements have the properties of their parent atom. The compounds do not have specific properties, and the properties vary with the bond type. Elements are formed with the same types of atoms.
For example, we are considering oxygen O 2.
