(a) Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 9.0 g. Silver has 47 electrons per
atom, and its molar mass is 107.87 g/mol.
(b) Imagine adding electrons to the pin until the negative charge has the very large value 1.00 mC. How many electrons are
added for every 10 electrons already present?
In a 1911 paper, Ernest Rutherford said: In order to
form some idea of the forces required to deflect an
alpha particle through a large angle, consider an
atom containing a point positive charge Ze at its
center and surrounded by a distribution of negative
electricity, – Ze uniformly distributed within a sphere
of radius R. Derive an expression for the magnitude
of the electric field at the center of the atom.
-
Express your answer using the parameters +Ze and
-Ze.
Hypothetical elements X and Y form a molecule XY2, in which both Y atoms are bonded to atom X (and not to one another). The X—X distance in the elemental form of X is 204 pm, and the Y—Y distance in elemental Y is 168 pm. What would you predict for the X—Y distance in the XY2 molecule? Explain your answer.
