If over 99.9% of an atom's mass is concentrated in the nucleus, the rest being "empty", why is matter (simply composed of atoms) clearly visible, rather than being largely invisible?

Also, why can't I move my hand through a solid table? Where is this empty space constituting the majority of the table?

Might be a silly question, but it's just a random thought that struck me
