Question

PP 2.5 (A) Using the one radil data in Appendix 2. calculate the color bic force of attraction between the Migh-ollon pair. (b) What is the repulsive force in this case? (See Examples 2.5 and 2.6.)

Answer 1

the force of attraction can be calculated as shown below in the image
When mitals and non metals forms compound then the mita mital atom donales electrons to atom which de a non metal here metal is Mgt2 & non mital is 0²- The face of attraction is given by - F = k ap 9/2 q, = charge on Metal qz z charge on non metal d = listance between ions nuclei in meter K = Proportionality Constant (8.99x 103 Nm²) i Ko 1/41 to 8.99x109 C q, 2+2 x charge on le = 2X 1.9 X 1079 C 2 3.88 1019c q2 2-2 X charge on le = 2(1.9801) 3.8 xlo-19 here - - - 4 = rote rolation so zanion Mg²+ = 0.078.nm = 0.078 X 109 m 02 0.132 nm - 0.132 X 109 m M = 0.072 +0.132 0.210nm = 0.210 X 10 - f = (B.99x109) 13.8 x1019) (3.8x1019) 10.2108 109) f = 8.99 x 3.8x3.8 x 10-29 0.210 x 0.210 X10-18
