SHAPES OF MOLECULES. REMINDER ABOUT ELECTRONS Electrons have negative charges Negative charges “repel” each other In molecules, electrons want to.
Drawing Lewis structures 1.Calculate the total number of valence electrons in the compound. 2.Choose the central atom and place the remaining atoms symmetrically.
