10If two atoms are bonded together, one with six valence electrons, the other with four, how many electrons must they share for both to achieve a full octet?
- A6
- B8
- C3
- D2

- DNone
- A1
12Explain why the Lewis structure for SF6 has twelve electrons around sulfur instead of eight.
- ASuch a Lewis structure violates the octet rule and is incorrect.
- BSulfur has a formal charge of -6 because S is in Group 6.
- CSulfur can have an expanded octet.
