Chemical Bonds Essay Physical Science

Chemical Bonds Essay

First I am going to tell you about the ionic bond. An ionic bond, bonds a metal and a nonmetal. Also in the ionic bond and electron is transferred, making a positive ion and a negative ion. The ionic bond makes solids with strong bonds, that are very hard to melt.  This bond also gains or loses an electron . For example the atom that takes the electron becomes a negative ion. Then the other atom loses an electron and becomes a positive ion. Finally it results in a repeating lattice pattern of ions. One example would be like salt (NACL).


Then I am going to tell you about the metallic bond. This bond, bonds a metal and metal. The metallic bond has an electron cloud around the atoms also known as the “Sea Of Electrons”. The atoms donate outside electrons to the whole group.They are a very good conductor of all states, lustrous, very high melting point. An example would be NA, FE,AL,AU and CO. To sum up the metallic  
bond share their electrons.

Finally I am going to tell you about Covalent Bonds. Covalent Bonds are formed by the sharing of electron pairs. For example Water (H2O). Thus bond, bonds a metal and a nonmetal. Between non-metal the elemnts have the similar electronegativity. However they are not good conductors of any state.
