Boron Trifluoride

[Adrienne_4F]

In our notes from October 31st, we drew boron trifluoride, but boron only has 6 electrons, why? Don't all elements need 8 electrons?

[Tyra Nguyen 4H]

I believe Boron is an exception to the octet rule! Just something to memorize:)

[Ethan Nishikawa 4D]

Yes boron is one of the elements that is part of the exception.

[Abhi4F]

Boron is one of the exceptions to the octet rule.

[Amy Dinh 1A]

That's why it's shape is trigonal planar.

[Tatum Keichline 2B]

B, Be, Li, H all exceptions to octet rule because they don't complete valence shell

[anishathomas]

Boron is one of the examples of elements that can have expanded octects. Also those that are 2p and lower can have expanded octects.

[Zubair Ahmed 1L]

Boron is an exception to the octet rule, just like any other element in group 13 such as Aluminum.

[KHuang1L]

Boron is one of the element exceptions that do not follow the octet rule. It is between the element carbon (which is the first element by increasing atomic number that requires a full octet) and beryllium (an element that does not follow the octet rule). Therefore, it also doesn't require an octet.
