Answer
Their outer energy levels are completely filled with electrons.
Explanation
Noble gases are elements found in the 18th group of the periodic table and are known for their lack of chemical reactivity. This characteristic is primarily due to their electron configuration. Each noble gas has its outermost energy level completely filled with electrons, which makes them stable. Atoms generally react to achieve a full outer electron shell, either by gaining, losing, or sharing electrons. Since noble gases already have a full valence shell, they have little tendency to engage in chemical reactions. This stability is a direct consequence of having their outer energy levels fully occupied by electrons, which satisfies the octet rule (or duet rule in the case of Helium) without the need for forming chemical bonds.The options provided suggest various conditions related to electron configurations and their influence on chemical reactivity. The correct answer is based on the fundamental understanding of atomic structure and electron distribution in shells or energy levels. - The statement about having no electrons is incorrect since all atoms have electrons.- The option stating they have seven electrons in the outer energy levels applies to halogens, not noble gases, which makes them very reactive as they seek to complete their octet.- The claim that their outer energy levels are completely filled with electrons accurately describes why noble gases do not form compounds readily.- The suggestion that they have empty outer energy levels is incorrect as that would make an element highly reactive, seeking to fill its outer shell, contrary to the nature of noble gases.
