Grade 12th passModern Physics

In scattering experiment, find the distance of closest approach, if a 6 MeV alpha-particle is used
1) 3.210^-16 m 2) 210^-14 m
3) 4.610^-15 m 4) 3.210^-15 m

I know the formula I am only confused about the value of Z to be substituted. please solve and explain properly !
