Question

How are the electron structures of boron (B) and aluminum (Al) similar?

A. They both have valence electrons in the second energy level.
B. They both have 3 electrons in each sublevel.
C. They both have 1 electron in a p orbital.
D. The highest sublevel that has electrons is the 3p sublevel.
my brain isn't functioning correctly. 2 days up working on homework lol

Answer 1

C: They both have 1 electron in a p orbital.

Step-by-step explanation:

Find the electron configuration of B

Boron is 1s 2s2 2p1

Find the electron configuration of Al

Aluminum is 1s2 2s2 2p6 3s2 2p1

If you look at the p orbital, they both have 1 electron.

Therefore, the correct answer is C.

Hope it helped!
