There are two types of elements, metals and non-metals. In chemistry there are four types of bonds that form compounds. Each of these bonds form different compounds that in turn have distinct properties, from high to low melting points. Elements combine to form thousands of compounds that have a series of different properties.
Primarily, there are two forms of elements, metals and non-metals. Metals tend to have a weak nucleus while in turn non-metals have a powerful nucleus, making them strong attractors. Metals, known as givers, have several clouds making them larger and impairing them from becoming strong attractors. Also, metals are found in the left part of the periodic table, non-metals in the right. Between the metals and non-metals are the metalloids they are not known as metal or non-metal. They are simply elements intermediate in properties between the typical metals and nonmetals.
Subsequently, there are four types of bonds that form compounds. The ionic bond is the combination of a weak metallic nucleus with a strong non-metal nucleus, which result in the transfer of electrons. Polar-covalent bonds are bonds formed from non-metals and metals, the non-metal attract electrons more efficiently but are not entirely able to remove the electrons. Hence leading to the unequal sharing of electrons held together by opposite attraction. A third type of bond is the Non polar-covalent bond. This bond is composed of two strong nuclei of equal strength that result in the sharing of electrons. Since the electrons are being shared equally there are no poles making the molecule neutral. The last type of bond is the metallic bond. The metallic bond is made of two weak nuclei with large clouds. The cloud is held together by the constant moving of electrons from large cloud to large cloud.
Moreover, these compounds have different properties. An ionic compound is polar charged, and has strong attraction.
