And also could you describe the properties of an ionic bond Please!

Ionic bond is a bond formed between two elements when they have an electronegativity difference of or more than 1.7. It is formed by an electrostatic attraction between the ions. One element forms the cation by loosing electrons while the other element forms anion by gaining the electrons. Then this separation of positive and negative charges creates an electrostatic force of attraction between the elements and  an ionic bond is formed. 
It is strongest in nature and  has small bonds.  

 covalent bond is formed by the sharing of electrons between two species of elements or compounds. It is of two types-polar and non-polar. 
When the covalent bond is between a highly electronegative element and a low electronegative element, then it is polar. If it is between two species of similar electronegativity, then it is non-polar. 
They are not as strong as ionic bond and are longer than ionic bonds.
