Problem 18

(a) Using the symmetry of the arrangement, show that the electric field at the center of the square in Figure 18.44 is zero if the charges on the four corners are exactly equal. (b) Show that this is also true for any combination of charges in which qa = qb and qb = qc

BIOL 300 Foundations of Biology – Telleen Section 3 pt 2  9. The number of neutrons in the nucleus of an atom can vary without changing the electrical properties of an atom. Isotopes are atoms with the same atomic number (# of protons) but have different numbers of neutrons (i.e. they have a different atomic mass)  10.Most elements are a mixture of isotopes. For example, Carbon (C) always has 6 protons (because its atomic # = 6), but the atomic mass of C can be 12, 13, or 14 (i.e. 6, 7, or 8 neutrons). 99% of C is 12C, but other forms do exist. 14C is unstable and results in radioactive decay. o D. Molecules are groups of atoms held together by energy through the formation of chemical bonds. There are three basic types of chemical bonds.  1. Ionic bonds are formed by the attraction of opposite electrical charges (+ attracts -, sort of like magnets). Sodium Chlorine (NaCl), or table salt, is a good example. NaCl forms a solid crystal as the Na and Cl ionize to form Na+ and Clions, which then attract each other due to their opposite electrical charges. Ionic bonds are fairly strong (though not as strong as covalent bonds), but are not directional (e.g. a positive charge can attract a negative charge from any direction; they are more promiscuous than covalent bonds).  2. Covalent bonds are the strongest chemical bond. They are forme
