Document Summary
The easternmost point of the united states is. Forces that hold groups of atoms together and make them function as a unit. It is the energy required to break a bond. It gives us information about the strength of a bonding interaction. A bond will form if the energy of the aggregate is lower than that of the separated atoms. The distance where the system energy is a minimum. A nonmetal and a metal react (ionic compound): metals lose electrons to form cations and achieve ngec; nonmetals gain electrons to form anions and achieve. Two nonmetals react (covalent compound): they share electrons to achieve ngec. Formed from electrostatic attractions of closely packed, oppositely charged ions. Formed when an atom that easily loses electrons (low ionization energy) reacts with one that has a easily gains electrons (high electron affinity) Q1 and q2 = numerical ion charges r = distance between ion centers (in nm)
