Chemical Bond

1. Ionic bond

Ionic bond (or bond elektrokovalen) is a type of chemical bonds that can be formed between the ion-ionlogam dengannon-metal (or polyatomic ions such as ammonium) through electrostatic attraction force. In other words, ionic bonds are formed from the force of attraction between two ions of different charge.For example in table salt (sodium chloride). Ketikanatr iu m (Na) and chlorine (Cl) joined, sodium atoms lose electrons, forming cations
(Na +), while the chlorine atoms accept electrons to form anions (Cl-). These ions then attract each other in a 1:1 ratio to form sodium chloride.Na + Cl → Na + + Cl-→ NaCl

2. Covalent bond

Covalent bond is a type of chemical bonds are characterized by pairs of electrons are mutually shared (joint venture of electrons) between atoms are bonded. In short, attraction and repulsion stability that forms between atoms when they share electrons is known as covalent bonds.Summarizes the many types of covalent bonding interaction, namely sigma bond, pi bond, metal bonding, interaction Agostic, and ties the three centers two electrons. The English word for a covalent bond, covalent bond, the first time.appeared in 1939. Awalanco-means jointly, associated in action, partnered, etc..; So that the "co-valent bond" means that the atoms share "valence", as discussed by the valence bond theory. In the H2 molecule, the hydrogen atoms share two electrons via covalent bonding. Covalency is greatest between atoms of similar electronegativities. Therefore, the covalent bond is a bond between two atoms.

same element, but only on their electronegativities. Therefore, covalent bonding is the sharing of electrons, the electrons are necessarily delocalized. Furthermore, in contrast to electrostatic interactions ("ionic bonds"), the strength of covalent bond depends on the angle relation between atoms in polyatomic molecules.
