4. Covalent Compounds - University of Hawaii at Manoa
A molecule or compound is made when two or more atoms form a chemical bond that links them together. As we have seen, there are two types of bonds: ionic bonds ...
The number of bonds that an element can form is determined by the number of electrons in its valence shell (Fig. 2.29.1). Similarly, the number of electrons in the valence shell also determines ion formation. The octet rule applies for covalent bonding, with a total of eight electrons the most desirable number of unshared or shared electrons in the outer valence shell. For example, carbon has an atomic number of six, with two electrons in shell 1 and four electrons in shell 2, its valence shell (see Fig. 2.29.1). This means that carbon needs four electrons to achieve an octet. Carbon is represented with four unpaired electrons (see Fig. 2.29.1). If carbon can share four electrons with other atoms, its valence shell will be full.

10. How do you determine if a substance is an ionic compound? - Socratic
Nov 16, 2016 · If the substance melts, then it is probably a covalent simple molecular substance (as shown in the table). However, if no melting occurs ...
Run it through a series of tests. Ionic, covalent (simple molecular and giant atomic), and metallic compounds all have different properties. Hence, to classify a substance as either one of such compounds, a series of tests/experiments must be carried out in order to figure out what properties it has. Observe the following table: Once the experiment has been carried out, the results that you obtain can be compared with those in the table to identify what sort of compound the substance is. First, a sample of the unknown substance can be placed in a test tube and put over a flame. This is done to determine the melting point. If the substance melts, then it is probably a covalent simple molecular substance (as shown in the table). However, if no melting occurs, the substance can either be ionic, covalent giant atomic, or metallic. This is really why we need to carry out more than one test on the unknown substance because some categories of compounds share similar properties (for example, ionic compounds and covalent compounds both have high melting points). Next, you can try to dissolve some of the substance in water (or another polar solvent). If it dissolves, then it can be either an ionic or covalent simple molecular compound. Your results from the previous test and the next will help to narrow down your results to just one type of compound. Next, you can connect the sample to a circuit like the one shown below to see if it conducts an electric current. You can replace the switch with the sample. If the bulb lights, then it's a conductor and if not, then it's a non-conductor. So, for example, at the end of this experiment, if the sample remained unmelted, dissolved in water and conducted an electric current, then it is an ionic compound. All of these observations can be further explained by examining the bonds and intermolecular forces of attraction that hold components of a compound together.

Aug 11, 2023 · A covalent bond forms when the bonded atoms have a lower total energy than that of widely separated atoms. polar covalent bond.
Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons. A bond forms when the bonded atoms have a lower total energy than that of widely separated atoms.
