Hi Leila,

VMD has a rich atom selection syntax, details of which can be found in the manual:
http://www.ks.uiuc.edu/Research/vmd/current/ug/node87.html#ug:topic:selections

It is worth going through the documentation for this. You'll find that your particular question can be addressed simply once you've obtained a little bit of background with VMD.

Best of luck,
Josh
