Question

knowledge check question 1
which statement is true?
most elements are not bonded to other elements.
atoms are more stable if their outer energy level is not full.
other than noble gases, the atoms in most elements are bonded to other atoms.
noble gases are always found bonded to other elements.
atoms are less stable if they outer energy level is full.

Explanation:

• Option 1: Most elements are bonded to other elements to achieve stability, so this is false.
• Option 2: Atoms are more stable when their outer energy level is full (octet rule), so this is false.
• Option 3: Noble gases have full outer energy levels and are stable on their own. Other elements bond to achieve a full outer level, so this is true.
• Option 4: Noble gases are stable on their own and not bonded to other elements, so this is false.
• Option 5: Atoms are more stable if their outer energy level is full, so this is false.

Answer:

Other than noble gases, the atoms in most elements are bonded to other atoms.
