according to the octet rule, most atoms in neutral compounds strive to have how many electrons in their valence shell?\n8\n10\n6\n4\nwhich of the following molecules is an exception to the octet rule because the central atom has fewer than eight valence electrons?\nco₂\nbf₃\nnh₃\nh₂o

Answer

Brief Explanations:

The octet rule states that most atoms in stable compounds strive to have 8 electrons in their valence shell. For the second - part, $BF_3$ is an exception as the boron atom in $BF_3$ has only 6 valence electrons. Hydrogen - containing molecules like $H_2$, $NH_3$, and $H_2O$ follow the octet rule for non - hydrogen atoms and the duet rule for hydrogen.

Answer:

  1. A. 8
  2. A. $BF_3$
