Document Summary
Textbook review of bonding unit 1 part a (basics) Bonding refers to the force(s) that hold particles in a particular position. The forces are based on the electrostatic attraction of + and particles (protons and electrons). Coulomb"s law is the scientific rule that explains bonding forces. Since bonding is all about attraction or repulsion, we are really interested in subatomic particles with charges. Protons found in nucleus with a positive (+) charge: protons are trapped" in the nucleus and can only be moved with extreme amounts of energy. Each horizontal row of the periodic table represents a new layer or level of electrons. All ionic compounds and some molecular compounds have strong intermolecular forces that make them form solids. Metals lose electron(s) and become positively charged (na+, zn2+. Non metals gain electron(s) and become negatively charged. (f-. Attraction of + and ions due to a transfer of one or more valence electrons (outermost electrons of an atom)
