Alpha particles can pass through very few materials. The spacing between nuclei of the material would have to be enormous for an alpha particle to pass through. The passage of alpha particles simply depends on the density of the material.
No
Alpha particles can pass through very few substances. It can travel in air but has a range of only a few centimetres.
Something that is selectively permeable allows some things to pass through it and not others
No
Glass, some plastics, air, water, and others.
Transparent materials will always allow light to pass through, translucent materials will allow light to pass through as well but the light rays will be scattered. Opaque materials will not allow any light to pass through.
yes, materials pass in and out of the nuclear envelope through the nuclear pores

Transparent materials allow light to freely pass through them. Translucent materials also allow light to pass through them, but change the colour of the light.
They stop.
Opaque materials do not allow light to pass through them.
