Electron dot diagrams are diagrams in which the valence electrons of an atom are shown as ⦠Solution Show Solution. They have distinct chemical structures characterized by a fixed ratio of atoms held together by chemical bonds. In this example the electrons are shown as dots and crosses. In Section 9.1 âLewis Electron Dot Diagrams,â we saw how ions are formed by losing electrons to make cations or by gaining electrons to form anions. Which of the following pairs will give displacement reactions? I this case from Mg to Cl. Ionic bonds are caused by electrons transferring from one atom to another. Thus, its electronic configuration is 2, 8, 2. Show the formation of MgO by the transfer of electrons in the two elements using electron dot structures. Write symbols of cation and anion present in MgO. Ionic bonds are caused by electrons transferring from one atom to another. Mg -1e- â Mg 2 + O + 2e- â O-2 Mg +2 + O-2 â MgO - Science. Cl - = 2,8 In sodium oxide molecule, two sodium atoms transfer their one electron to one oxygen atom to form ionic bonds During the bond formation between Magnesium and Oxygen, one Magnesium atom loses two electrons to Oxygen atom. Magnesium is in group 2 of the periodic table. (ii) Show the formation of and by the transfer of electrons. Question 1. Answer:-(i) The representation of elements with valence electrons as dots around the elements is referred to as electron-dot structure for elements. The chemical equations involved in the process are given below. Thus, its electronic configuration is 2, 8, 7. Show the Formation of Na2o by the Transfer of Electrons Between the Combining Atoms. It is two electrons short of octet configuration, thus it will gain two electrons. We saw this in the formation of NaCl. The electron configuration of Mg is [Ne]3s².
