Question

what if we could see air, i mean the atoms but could pass through them​

Answer 1

Explanation:

1. When two atoms touch i.e, their outer orbits come near each other then generally they share their electrons to form bonding and acquire a more stable state. In case of physical touching which is generally not possible as the outer shell electrons repel each other.

Answer 2

To explain why we must look at the electrons. Unfortunately, much of what we are taught at school is simplified – electrons do not orbit the centre of an atom like planets around the sun, like you may have been taught. Instead, think of electrons like a swarm of bees or birds, where the individual motions are too fast to track, but you still see the shape of the overall swarm.
