Elements with a filled outermost energy level are considered to be stable due to the full complement of electrons. These elements typically fall under the noble gases group in the Periodic Table, such as helium, neon, argon, krypton, xenon, and radon. The filled outermost energy level results in these elements having little to no reactivity with other elements, making them chemically inert.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.

An atom with an incompletely filled outermost energy level is likely to be reactive. This is because atoms tend to gain, lose, or share electrons to achieve a stable outer electron configuration. Atoms with incomplete outermost energy levels are looking to fill or empty their outermost energy level to achieve stability.
Eight electrons represent a complete (filled) outermost energy level for elements heavier than boron. This is because the outermost energy level can hold a maximum of 8 electrons according to the octet rule.
The column on the periodic table that contains elements with completely filled outer energy levels is the noble gases column (group 18 or Group 8A). These elements have a full outermost energy level, making them stable and less likely to form bonds with other elements.
Because their outermost energy level is only partially filled, some elements are highly reactive, I believe.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Helium only needs two electrons to have a filled outermost energy level.
