which statements about the chemical stability of atoms is true?
fluorine is stable when its outer energy level has seven electrons.
sulfur is stable when its outer energy level has eight electrons.
hydrogen is stable when its outer energy level has two electrons.
group 15 elements are stable when their outer energy levels have five electrons.
group 17 elements are stable when their outer energy levels have eight electrons.

Explanation:

• For fluorine (Group 17), it is stable when its outer energy level has eight electrons (octet rule).
• Sulfur (Group 16) is stable when its outer energy level has eight electrons (not seven).
• Hydrogen is stable when its outer energy level has two electrons (duplet rule, not eight).
• Group 15 elements are stable when their outer energy levels have eight electrons (not five).
• Group 17 elements are stable when their outer energy levels have eight electrons (not five).

Answer:

None of the given options are correct.
