Answer:
The characteristic of silicon that is most closely related to its chemical reactivity is that;
It is found in nature in mainly as oxides and silicates
Explanation:
Silicon, which is a member of group 14 of the periodic table has the electron configuration of [Ne]3s²3p² and has a high affinity for oxygen such that the the oxides are known as silicates and it is almost impossible to find pure silicon in nature and it is found in the universe as silica and silicates
Silicate minerals make up over 90% of the Earth's crust such that, by mass silicon is only surpassed by oxygen as the most abundant element found in the Earth's crust.

The electron, due to the way an electron orbits the nucleus of an atom.
According to Quantum Mechanics, electrons do not really orbit the nucleus of an atom. In fact, the most tightly bound state, the 1s orbital, has no angular momentum at all. This would be the state with the most "kinetic energy" and yet there is no "orbital" motion at all in this state.
