Example: Lewis structure of the nitrite ion. 1  Step one: Nitrogen is the least electronegative atom, so it is the central atom by multiple criteria. 2  Step two: Count valence electrons. Nitrogen has 5 valence electrons; each oxygen has 6, for a total of (6 Ã 2) + 5 = 17.
So I cooked eggs at each of these temperatures for times ranging from 45 minutes to 2 hours. The testing showed that indeed timing does matter, though the most noticeable effects are with the egg yolks. For instance, an egg cooked at 145Â°F for 45 minutes will have a barely set white and a completely liquid yolk.
DIRECTIONS. 1  Mix together the flour and salt. 2  Add the oil, and then slowly add the water until you reach a nice clay consistency that you like. If you want the clay colored, this is the time to add the food coloring! 3  Mold into whatever shapes that you want. If using egg yolk brush it on now.  Pre-heat the oven to 250 degrees.
