I'm not sure how to draw it. This agent can be used as a countermeasure for exposure to strontium and radium radionuclides. c) Sodium + Oxygen. Lewis Dot Structure: In simple words, the indication of each individual valance electrons of the atom or molecule of a chemical element or a chemical substance is done by their Lewis dot structure. I'm supposed to draw the lewis structure for P4. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium (Ra-226) and strontium in the gastrointestinal (GI) tract. Recalculating the FC, the double bonded oxygen has a charge of 0, the Phosphorus has a charge of 0, and the other 3 oxygens are still at -1. ... Br :" Phosphorus surrounded by 6 electrons, Bromine surrounded by 7. As such, because there are more elements with a charge of 0, this structure with a double bond is more stable. Again, it does not matter on which sides of the symbol the electron dots are positioned. Based on your electron configuration, the element that you want to draw is Phosphorus, since you have 15 electrons.Phosphorus has 5 valence electrons.. To draw Lewis Structures for elements, the symbol for the element is drawn with the number of valence electrons it has surrounding it. More complicated molecules are depicted this way as well. Electrons. Is phosphorus a polymer with a complex structure? As usual, we will draw two dots together on one side, to represent the 2s electrons. a) Sodium + Chlorine. Draw a. How can we construct the POCl 3 resonance Lewis dot structure?
