Data storage in an SSD

[AdityaDev]

I am still in high school but my curiosity is not stopping me from posting in this forum.
How is data stored in SSD? How does it differ from the old HDD? I heard that atoms are used to store data. How?
Binary consists of 0 and 1. How does someone use an atom to represent 0 and 1?
Does positive ions represent 1 and negative ions represent 0?

If you google for "solid state drive" you will get a bunch of hits including a wikipedia page. Read that, then come back with more specific questions.
