Document Summary
Bonds are broken and bonds are made. We will need at least 2 semesters of your time to answer this question. Plastics: 1. 2 structural theory, in the mid 1800s, it was first suggested that substances are defined by a specific arrangement of atoms. Attractive forces between positively charged nuclei and negatively charged electrons nuclei. Repulsive forces between the two positively charged. Repulsive forces between the two negatively charged electrons: 1. 3 atomic structure, a review from general chemistry. Protons (+1 charge) and neutrons (neutral) reside in the nucleus. Electrons (-1 charge) reside in orbitals outside the nucleus. Valence electrons are the electrons in the outermost shell. Practice with skillbuilder 1. 2: 1. 3 simple lewis structures, for simple lewis structures . Take nh3, for example : note the nitrogen has a lone pair of electrons, 1. 3 simple lewis structures, for simple lewis structures . Draw the individual atoms using dots to represent the valence electrons.
