![]() ![]() Since Mg lost two electrons, it becomes cationic with +2 positive charge and Cl becomes Cl- by gaining one electron. Now, the electron configuration of Mg will be:Īnd, the electron configuration of each Cl atom becomes: Magnesium will transfer each of its valence electrons to both the Cl atoms. If we put the valence electrons accordingly, the sketch looks like this:īoth the Chlorine atoms are only one electron short of achieving the octet configuration whereas Mg has only 2 valence electrons. Octet Rule: The main group elements present in groups 1-17 tend to have the valence shell octet configuration of the noble gas elements. In covalent bonds, we see sharing of electron pairs but in ionic bonds, we will see electron transfer.īut in both cases, we work towards the fulfillment of the octet i.e. This combination results in an ionic compound and therefore the bond type is ionic and not covalent. Chlorine, on the other hand, is a halogen and therefore a non-metal. ![]() Magnesium, as we all know, is an alkaline earth metal. The total number of valence electrons in a molecule of magnesium chloride = 2*1 + 7*2 = 16. Mg has 2 valence electrons whereas Cl has 7 valence electrons. As we can see, Mg belongs to group 2 and has an atomic number of 12 whereas Cl belongs to group 17 and has an atomic number of 17. Let us now draw the Lewis Structure diagram for MgCl2. This is therefore a 2D graphical representation of a molecule where we find out the type of bonds that are present in between atomic elements. To find the most suitable Lewis Structure of a given molecule or ionic composition, we have to sketch skeletal electron-dot diagrams of the constituent elements along with their valence electrons (electrons present in the outermost shell). Lewis Structure is the first and foremost step towards understanding the concept of bonding. Here, in this article, we will discuss the nature of chemical bonding inside a molecule of MgCl2. We can also get an idea about the chemical and physical properties of a compound from this concept. The study of atomic attraction that results in the formation of products is known as chemical bonding.Ĭhemical bonding is an interesting and notable concept of chemistry and we have several types of bonds to discuss and understand. And if we reverse this situation and we have MG to positive plus two electrons gives us MG.In this universe, we have a vast range of elements that come together to create different varieties of chemical compounds.Ītoms get attracted and form several molecules of varied chemical composition. So the delta X value corresponds to this is equal to minus +2337 minus +23 3 7 kg. So the third equation will be formed similarly, the if we put that is MG we I haven't just converted into MG two positive plus two electrons. That is if we reverse this equation to and again multiplied by two. And actually it is the reverse equation of two multiplied by two. So this value corresponds to -100 sorry, -480 kg of basically this is the third equation. ![]() So this is the second equation now to L two cl negative is converted into two cl negative is converted into cl two plus two electrons. So this is the equation one equation, one, so now half one by two cr 21 by two Cr two plus electron gives us gives us cl negative ions and delta X value for this is equal to 2 40 kg to 40 kg. So delta X is equal to minus 643 -643 kg. ![]() So MG that is magnesium Plus CL two Cierto gives us MGs here to give us mg cr two. So the delta X value that we have to calculate that we have to calculate. So we know that MG two positive mg to positive blurs to cl negative gives us mg cr two MG cr two. So yeah, starting from its relations with the basically latest energy of MG cR two learn this energy empty cl clue. ![]()
