Formation of ionic bond takes when an electron is transferred from a non metal to metal making the two atoms have partial positive and negative charge hence they attract one another.
Reaction between non-metals and metals results into electrons being transferred from the metal to non-metal and, therefore, the metal and non-metal forms ions. On the other hand, the compound formed is called an ionic compound (Gaskell 2008, p. 17).
In the above example, sodium atom loses an electron to the chlorine atom. Therefore, sodium atom, therefore, becomes partially positively charged while the chlorine atom becomes partially negatively charged hence an ionic bond is formed (Gaskell 2008, p. 18).
Ionic bonds do not have a definite shape while covalent bonds have definite shapes that can be predicted. In addition, covalent bonds can be broken to the original atoms which made the molecule because the atoms are close to one another so as to share electrons (Engel and Reid 2012, p.43).
While, ionic bonds are solid, covalent bonds molecules are gaseous or liquids. Compounds that have covalent bonds have a lower melting point than ionic bonds because they have weak van der waals forces that do not require a high amount of energy. On the other hand, ionic compound has higher melting points because their bonds are stable and hence high amount of energy is required to the bonds (Atkins & Paula 2012, p.54).
Ionic bonds also form crystalline atoms and in solution or molten state they conduct electricity and are also polar bonds. Therefore, most of them dissolve in water but are insoluble in solvents that are not polar (Silbey et al. 2004 p.30).
Ionic bonds are formed between a metal and non-metal atoms. For the formation of the bond to occur, the atoms must have high difference in electron negativity and it is made when the metal atom loses an electron to the non-metal making it

One of the main features of such polymers is low, controllable viscosity which can be adjusted through the introduction of monomeric units possessing the ability to interact with the chain stoppers. The main purpose of the work was to isolate small receptor molecules which contained AADD hydrogen bonding in their structure.
On the other hand, a compound is made of two or more elements held together by chemical bonds (Leong & Aik, 2009). The differences between mixtures and compounds are discussed below: A mixture lacks fixed composition while a compound has a fixed composition.
It also describes how to differentiate an element and a compound despite being pure substances by results from decomposition. In the paper the metals, non-metals, and transitional elements are discussed to demonstrate the bonds. Ionic bonding formed between metals and non metals are explained and illustrated.
One way to distinguish between mixtures and compounds is through the law of constant composition which states that the ratio by mass of the elements in chemical compound is always the same regardless of the source of the compound (“Elements, Compounds and
These in turn determine the physical tendencies of the metal. The periodic table presents these differences. Compounds are arranged such that elements with common chemical properties and reactions belong in
Ionic bonding defines cohesive forces between atoms of different chemical elements because of ions of opposite charged that attract one another. The bonding forms between two elements such that atoms in one of the elements lose electrons from
From the knowledge of how the elements combine, we can then be able to explain specific characteristics that are observed in different substances all around us. Deeper understanding can even assist in the
