  • Difference between Cation and Anion

    A cation is an ion that has a positive charge and an anion is an ion that has a negative charge. Both cations and anions are types of ions. An ion is an atom or group of atoms that have an electrical charge,…

  • Metallic Bond Examples

    Metallic bonds are a type of chemical bond that occurs between atoms of the same metal. Through these links, very compact structures are achieved, since the nuclei of the atoms come together so much that they begin to share their valence electrons. For example bonds between aluminum…

  • Enthalpy and Internal Energy

    Enthalpy is the amount of heat absorbed during a chemical reaction, while Internal energy is the sum of kinetic energy and potential energy. Enthalpy is represented by “H”, while internal energy is represented by “E”. More differences between Enthalpy and…

  • Difference between Oxidation and Reduction

    Oxidation is a reaction where an atom, ion, or molecule loses electrons while reduction corresponds to an atom, ion or molecule gaining electrons. Both oxidation and reduction depend on the change in the oxidation state of the atom, that is, on the difference in…

  • Ionic Bond Examples

    To form the molecules of chemical compounds, the atoms of different substances or elements must combine with each other in a stable way. This can happen in various ways by virtue of the structural characteristics that every atom has (consisting of a positively charged nucleus surrounded…

  • Covalent Bond Examples

    This post includes: Covalent Bond Definition Properties of Covalent Bond Types of Covalent Bond Examples of Covalent Bond Much more … Keep Reading … What is Covalent Bond? Covalent bonds are the bonds that are formed between two non-metals and that can…

  • Difference between element and compound

    In chemistry, A chemical element is a product made up of atoms of the same class, it is the simplest form of matter while a compound is a substance formed by the union of two or more elements. keep reading……

  • Difference between Metals and Non Metals in tabular form

    All known matter is made up of atoms, from the 112 chemical elements that make up the periodic table. These elements are classified, according to their nature and properties, into metals and nonmetals. Only 25 of the 112 elements are metallic, generally coming from minerals and with…

  • Difference between Pure Substance and Mixture

    The Difference between Pure Substance and Mixture is given here. For chemistry, a pure substance is one whose chemical composition is homogeneous while a mixture is the union of various substances with different properties that do not react chemically. keep…

  • What are Some Examples of Physical Changes?

    Physical changes are modifications or transformations that occur in any matter but do not imply a change in its nature or composition. The latter would imply a chemical change. Common Examples of Physical changes are the breaking of glass, mixing…
