Covalent bonds are one of the types of bonds found between elements. Its different from ionic bonds because these elements don't take electrons. Why would this bond not take electrons tho? It is a good question and the reason is the electronegativity. First of all, all elements want to reach eight valence electrons, and it becomes unusually stable such as the noble gases. The element's electronegativity is the pull it has on other electrons to fulfill the octet rule. Covalent bonds are different because it shares electrons. Two nonmetals will usually be the two elements combing with each other. Electronegativity takes it affect because if both have roughly the same amount of it, then the two elements must share than steal because neither can steal from one another. A property that can differ from ionic bonds are a much lower melting and boiling point. This is because ionic bonds need to be melted all the way because of their negative and positive charges, but covalent bonds are not that tightly packed and requires much less energy to make physical changes. Another property is covalent bonds are more flammable. It is because of the specific bondings of carbon and hydrogen atoms. These two properties are usually true for covalent bonds, but there can be exceptions to these rules.
I found this web page rather interesting especially for covalent bonds. It was very informative and told me the important parts of any kind of information. If anyone were curious in covalent bonds, this would be the first place I'd tell them to look. The different bonds are important to know because our industries help create useful materials from making bonds of different elements. This knowledge is another tool for a productive use in our everyday lives.
