Forming ions - Bonding - OCR Gateway - GCSE Chemistry.
A chemical bond is the energy that holds two atoms together in a compound. This energy can be further broken down into ionic bonding and covalent bonding. An ionic bond is a chemical bond characterized by attraction between ions of opposite charge.
Chemical bonds hold molecules together and create temporary connections that are essential to life. Types of chemical bonds including covalent, ionic, and hydrogen bonds and London dispersion forces.
A nonpolar molecule is a bond between two identical atoms. They are the ideal example of a covalent bond. Some examples are nitrogen gas (N 2), oxygen gas (O 2), and hydrogen gas (H 2). One way to figure out what type of bond a molecule has is by determining the difference of the electronegativity values of the molecules.
Ionic Bonds. One type of chemical bond is an ionic bond. Ionic bonds are formed by the electrostatic attraction of atoms that have opposite charges. An ion is an atom that has gained or lost one or more of its electrons in its outer shell, therefore giving the atom either a positive or negative charge.
Definition noun, plural: chemical bonds The attractive force that binds atoms, ions, or molecules in a chemical compound Supplement A chemical bond is a bond that holds atoms together. It is the force that binds ions or molecules together. It helps form a chemical compound. Examples of the chemical compounds that are of special interest to biologists are water, sodium chloride, and carbon.
Chemical bonds: This pictures shows examples of chemical bonding using Lewis dot notation. Hydrogen and carbon are not bonded, while in water there is a single bond between each hydrogen and oxygen. Bonds, especially covalent bonds, are often represented as lines between bonded atoms. Acetylene has a triple bond, a special type of covalent bond that will be discussed later. Covalent Bonds.
A chemical bond is the physical process that causes atoms and molecules to be attracted to each other and held together in more stable chemical compounds. Atoms are more reactive, and therefore more likely to bond, when their outer electron orbitals are not full. Atoms are less reactive when these outer orbitals contain the maximum number of electrons. This explains why the noble gases do not.
