The longest in geological time is an Eon eg. Archeozoic Eon .
Edit: there is also the supereon, which is usually composed of 2-3 eons.

A subshell is a subdivision of electron shells.
The scientific time scale is also called the Geologic time scale. It has been created to describe the order of major events on Earth for the last 4.5 billion years.

The longest subdivision in geologic time is the eon, which is further divided into eras. Eons represent the largest interval of time in the geologic time scale, such as the Phanerozoic eon which encompasses the last 541 million years.
Eons are the longest subdivision of geologic time. They are typically divided into eras, which are further divided into periods, epochs, and ages. Eons represent the largest time divisions in the geologic time scale.
The Precambrian
Eon The largest expanse of time on the geologic time scale is the eon. An eon would encompass at least two eras.
Eon The largest expanse of time on the geologic time scale is the eon. An eon would encompass at least two eras.
Eons I believe. Hope that helped! =)
The third largest division of geologic time is an era. The eras are further divided into periods, epochs, and ages.
Eon
In geologic time, the Hadean is the first EONof Earth's history, from it's formation 4.57 billion years ago to about 4 billion years ago. The Hadean is not an era, which is a smaller subdivision of geologic time.
The largest expanse of time on the geologic time scale is the eon, which is further divided into eras. Eons are the longest subdivisions of time, representing billions of years of Earth's history.
An eon is the largest division of geologic time, lasting billions of years. An era is a subdivision of an eon, typically lasting hundreds of millions of years. A period is a smaller division of geologic time, lasting millions of years, and an epoch is an even smaller division of time, typically lasting tens of millions of years.
Eon.
