(a) Li [He]2s1
(b) (i) LiCl(s)----LiCl(g)
LiCl(g)----Li(g)+Cl(g)
Li(g)----Li*(g)
Li*(g)----Li(g)+hv(red light)
(ii) According to Rydberg equation,1/wavelength = R(1/n1^2-1/n2^2) R=1.0973731568539(55) x 107 m-1,n1=2,and the visible red light has a wavelength of about 650 nm,solve the equation,we get n2=3,hence the transition of energy level is from n=2 to n=3
