Step 1
: Determine the number of electrons in a B+ 2 ion

The atomic number of Boron (B) is 5, which means it has 5 electrons. Since we are considering B+ 2, we have to remove 2 electrons from a neutral Boron atom. So, B+ 2 has 3 electrons.

Step 2
: Write the core electrons configuration

Boron is in the 3rd period of the periodic table, so its core electrons configuration is [He] 2s² 2p⁰, where [He] represents the Helium noble gas core configuration (1s²).

Final Answer

: Assign the electrons to the molecular orbitals
