Answer» Electrostatic force F = q1q2/(4πϵor2)Let q1 = q2 = ne where n is the number of electrons missing from each atom and e the charge on an electron = 1.6 x 10^-19C.1/(4πϵo) = 9 x 10^9N.m2/C2.r = 5 x 10^-10m F = 3.7 x 10^-9N = n2. (1.6 x 10-19C)2x 9 x109N.m2/C2/(5 x 10-10m)2. ⇒ n2=3.7 x 10^-9N x(5 x 10-10m)^2/(1.6 x 10-19C)2x 9 x109N.m2/C2. = 4⇒ n = 2 The number of electrons missing from each atom = 2 |
