Difference between element and compound

Difference between element and compound :Elements are the pure form of matter that are made of the same type of particles(i.e atoms), for example, hydrogen, oxygen, iron, copper, etc.One molecule of Hydrogen gas is made of two hydrogen atoms, therefore hydrogen is an element. Compounds are the pure form of matter that is made of different types of particles(i.e atoms), for example, water, carbon dioxide, sulfur dioxide, glucose, etc.One molecule of carbon dioxide is made of one carbon and two oxygen atoms, therefore carbon dioxide is a compound.

Elements:

Elements are divided into three categories. Metals, non-metals, and sub-metals.
Metals: The maximum number of elements in nature are metals. Metals remain in solid state in nature, most metals are very reactive, that is why most metals remain in nature in the form of ores. Examples of metals: Iron, copper, gold, silver etc.

Nonmetals: Nonmetals are present in small amounts in nature. Except diamond and graphite, all non-metals remain in gaseous state eg: nitrogen, oxygen, hydrogen etc.

Metalloids: These are the elements whose properties are between nonmetals and metals. Metalloids have some properties of metals and some properties of nonmetals. Example: Boron, Silicon, Germanium etc.

Difference between elements and compounds: A molecule of an element is made of similar atoms while a compound is made of dissimilar atoms.

Compound

Compounds are defined as substances that are formed when two or more elements combine with each other chemically, the elements in the compound combine with each other in definite proportions. A compound consists of two or more elements and different types of elements in a definite ratio of atoms. In a compound the individual properties of the elements are totally abolished and the substances formed from the elements have different properties.
Chemical Formula: Compounds are shown by chemical formula. The chemical formula shows the ratio of atoms present in the compound.

Example: The chemical formula for table salt is NaCl and the chemical formula for table soda is NaHCO3.

Types of Compounds

Generally Compounds are classified into two categories: Ionic Compounds and molecular compounds.

Molecular Compounds – In these compounds, the atoms bind each other through covalent bonds.Examples of Molecular Compounds are Methane,Carbon dioxide,Water etc.
Ionic Compounds – The atoms in Ionic Compounds are bound together through ionic bonds.
Examples of Ionic compounds are Sodium Chloride water,Potassium nitrate,Sodium hydroxide etc.

When we talk about molecules, these always refer to non-metals because in metals one atom is bonded to another atom by an ionic bond while a molecule is always formed through a covalent bond,as an example molecule of hydrogen gas.

oxygen molecule

ElementCompound
Elements are substances that are pure in their natural state and are composed of a single atom.Compounds are also pure substances that are composed disimilar atoms which are chemically joined to each other in definite proportions .
There are 118 elements which have been discovered so far out of which 94 elements are naturally occurring on Earth.Since compounds are formed from the elements so Infinite number of compounds can be formed. They can be infinite in numbers.
Elements are classified in three category metals, metalloids, and nonmetals.Compounds are classified into three categories:Metallic, ionic, and molecular.
Elements are the made of same types of atoms. Hence they cannot be broken downCompounds are made of disimilar atoms so hey can be broken down using chemical reactions.
They are represented by using numbers and symbols.They are represented by using chemical formulas.
Examples:Iron,Copper, hydrogen, oxygen, copper, boron etc.Example: Iron oxide,Baking soda,water, ammonia, sodium chloride.
