Chemical Bonding is the force of attraction between atoms and ion. It occurs when atoms happen to be transferring valence electrons which are electrons in the outer energy Level of an atom. Atoms are held together by Chemical Bonding. By sharing the electron, Atom has the ability to stay stable. Chemical Compound is composed or created of two or more separate elements. (H2O) Is an example of a chemical compound. They consist of ration fixed which is 2:1. (2;1) represents the two hydrogens that share electrons to oxygen. Furthermore, There are different types of bonding such as Ionic, covalent and metallic bonding.
Ionic Bonding is the force attraction that can hold together the positive and negative ions. It exists when a metallic element gives up the electron to an atom of nonmetal element. When this happens, the atoms become oppositely charged ions. As an example, sodium(Na) atom donate one electron to the atom of chlorine(Cl). Now, these two elements have equal but opposite charge. As a result, they cling together by a strong ionic bond. Ionic bond forms only between metal and nonmetal elements. You can remember Ionic bonding very easily by thinking that metal wants to give up electron and nonmetal want to gain.
Covalent bonding is the force of attraction that holds together a pair of electron. The bond is formed because they want to share together to become more stable. In some cases, electrons are not shared equally between the two atoms. This is called polar which is the condition when the electrons are not shared together equally. One of the examples is the polar covalent bonding of water. As a result, oxygen attracts more strongly than the hydrogen because they have attracts positively charged atom.
