Creating Electron Dot Diagrams
Order the steps to take when drawing electron dot diagrams.
Count the dots to make sure that all of the valence electrons are represented.
Draw dots around the chemical symbol to represent the valence electrons of the atom.
Use the periodic table to find the chemical symbol of the atom and the number of electrons in the valence shell.
Write the chemical symbol of the atom.

Aspecial electronic sensor is embedded in the seat of a car that takes riders around a circular loop-the-loop ride at an amusement park. the sensor measures the magnitude of the normal force that the seat exerts on a rider. the loop-the-loop ride is in the vertical plane and its radius is 23 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads 740 n. at the top of the loop, the rider is upside down and moving, and the sensor reads 370 n. what is the speed of the rider at the top of the loop?
