The two atoms have these Lewis electron dot diagrams and electron configurations: For the Na atom to obtain an octet, it must lose an electron; for the Cl atom to gain an octet, it must gain an electron. The basic idea in molecular shapes is called valence shell electron pair repulsion (VSEPR). Thus we need two Cl atoms to accept the two electrons from one Ca atom. So, the total lone pair is 6 that makes 6*2 = 12 unshared electrons. Element Common Oxidation Number(s) Rubidium Sulfur Arsenic Bismuth Strontium Tin Cadmium (+2) Phosphorous Zinc (+2) Silver (+1) . The kernel of the atom, i.e., the nucleus together with the inner electrons, is represented by the chemical symbol, and only the valence electrons are drawn as dots . In chemistry, drawing Lewis dot structures can be challenging, but they provide a wealth of information about the molecules they represent. If we were to follow these steps for the compound formaldehyde (CH2O), we would get the following: The H and O atoms have the proper number of electrons, but the C atom has only six electrons around it, not the eight electrons for an octet. Lattice energy depends on the charge and radii of the ions. It deliberately informs that Ba donates its two electrons to sulphur as it also has six electrons in the outermost shell of elections and it needs two electron to fulfil octet. Although the electron groups are oriented in the shape of a tetrahedron, from a molecular geometry perspective, the shape of NH3 is trigonal pyramidal. 3 .
