Main differences between Atom 1.0 and RSS 2.0 are:

Atom has separate "summary" and "content" elements, while RSS only has one "description" element.
Atom standardizes auto-discovery in contrast to the many non-standard variants used with RSS 2.0.
In Atom, it is mandatory that each entry have a globally unique ID, which is important for reliable updating of entries.
Atom 1.0 allows standalone Atom Entry documents whereas with RSS 2.0 only full feed documents are supported.
Atom specifies that dates be in the format described in a newer international standard, ISO 8601. The date format in RSS 2.0 was an older standard RFC 822.
