A completley filled out electron level makes the atom stable
cellular level
Stable.
An atom is the smallest particle of matter that still retains the characteristics of the original matter. Within an atom, protons, neutrons, and electrons make up the basic building blocks of elements.

all the way down to the smallest and then some
Species is the smallest level of classification in biology.
Yes, MOST matter is extremely stable. There are exceptions however, the most obvious of which is uranium (there are plenty of other unstable elements (elements with an extremely short half-life), but uranium has become popularized because it is one of the most unstable). Matter that is particularly unstable is used in nuclear reactions, because it is much easier to split than stable matter. For example, although there is enough matter in a piece of chalk that if transformed into pure energy would level a city, the atoms are so stable that it is seemingly impossible to release this energy.

Tertiary Level
At the smallest level, matter is made up of atoms, which consist of protons, neutrons, and electrons. Breaking matter down further would involve subatomic particles such as quarks and leptons.
you hae to be level 9 :)
cellular level
Order
No. Only members can jump. If you are a member, then yes, you must advance to a certain level. But if you are non-member, it does not matter. You will never be allowed to jump unless you become a member.
