Diameter of an atom formula
WebAtomic Radius. Unlike a ball, an atom does not have a fixed radius. The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance. As you can see from the diagrams, the same atom could be found to have a different radius depending on what was around it. WebAug 2, 2024 · For example, if your circle has a circumference of 23 inches, the diameter would be 23/π, or approximately 7.32 inches. If you only know the area of the circle, use the formula diameter = 2 x √(area/π). So, if the area of the circle is 25 square centimeters, the diameter would be 2 x √(25/π), or approximately 5.64 centimeters.
