Drawing radical cation

Hello,

Could you tell me how to draw a "radical cation" rather than a neutral molecule

on the 3D Atomistic Document? (e.g *CH2CN, where * means "an unpaired electron")

Also, if possible, could you also tell me how to draw positive(or negative) ion

on the 3D Atomistic Document?

Thank you in advance.

Best regards,

Nathan Shin
