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.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
