Because their outermost energy level is only partially filled, some elements are highly reactive, I believe.
reactive
Transition metals are the ones that can form ionic bonds by losing electrons from both the outermost and next to outermost principal energy levels. This is because transition metals have multiple oxidation states due to the presence of partially filled d-orbitals. By losing electrons from different energy levels, these metals can achieve a stable configuration.
These elements are referred to as transition metals. They have partially filled d orbitals in their outermost energy levels, which gives them unique chemical properties and allows them to form colorful compounds. Transition metals are typically found in the middle section of the periodic table.
They are called transition elements or transition metals. These elements have partially filled d or f orbitals, which lead to unique properties such as variable oxidation states and the ability to form colored compounds.

name the group of elements that have only one electron in their outermost energy level
The noble gas elements have outermost energy levels with full s and p orbitals.
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.

Some elements are highly reactive because their outermost energy levels are only partially filled, and they seek to gain or lose electrons to achieve a stable electron configuration. This can lead to the formation of chemical bonds with other elements in order to reach a more stable state.
These elements are called p-block elements because their outermost electrons are in the p orbital. In the groups 13 to 18, the electrons fill the p sublevel in the outermost energy level of the atom, which gives these elements their unique properties.
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.
