Explanation / Answer

C)
miu = Q*r
3.44*10^-30 Cm = Q*1.27*10^-10
Q = 2.71*10^-20 C
Answer: 2.71*10^-20

D)
Charge of 1 electron = 1.6*10^-19 C

percent ionic character = Q*100 / charge of 1 electron
                                                = (2.71*10^-20)*100 / (1.6*10^-19)
                                                = 16.9 %

Answer: 16.9 %
