Thermal conductivity of sodium chloride as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K (−265.15 °C; −445.27 °F) and decreases to 0.069 at … WebDrawing Lewis Structure Steps 1. Central Step: Select the central atom (the one that there is 1 of OR the least electronegative element if there is one of all). 2. Inventory Step: Count the total number of valence electrons in the molecule. Usually, its easier to divide by 2 and work with pairs of electrons. 3. Connect Step: Connect the surrounding (terminal) atoms …
