Boron is an exception to the octet rule and can take up to 10 electrons in its valence shell. True
False

Considering the exception to the octet rule, the statement is false because Boron is an exception to the octet rule and can take up to 6 electrons in its valence shell.

An exception to the octet rule is when there are too few valence electrons resulting in an incomplete octet. That is, the default exceptions imply that there can be covalently bonded atoms that surround themselves with fewer than eight electrons.

This exception occurs with boron. Boron has an incomplete octet because it only has six electrons around it. That is, boron has three valence electrons and can only form electron pair bonds in two locations, gaining stability only with 6 valence electrons.

In summary, the statement is false because Boron is an exception to the octet rule and can take up to 6 electrons in its valence shell.

False

Explanation:

Boron is an exception to the octet rule because it possesses less than eight electrons. Boron has five electrons with three of them being valence electrons and therefore has an incomplete octet. It readily forms compounds in which it has six valence electrons, rather than the usual eight.

Hope that helps.

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )
