Lewis Dots and Ions Name: Per Complete the table below. Aluminum is done as an example. Solar System Model: Use the chemical symbol to represent the nucleus; draw all electrons in their correct shell. Lewis Dot Notation: Write the chemical symbol, then place dots for the valence electrons around the symbol. (Draw them on the sides of an imaginary box.) Remember: # valence electrons = group # Rule of 8: Does the atom need to gain or lose electrons to gain a full (or empty) valence shell? How many clectrons? Remember: metals are losers. Ionic Charge: Determine the ionic charge of each ion. ("lon" = a charged particle.) add a -1 charge for each electron gained and a +1 charge for each electron lost. lon Notation: Write the chemical symbol, then the ionic charge as an exponent (above and to the right).
