Problem: Write the electron configurations for the following atoms or ions:a. B3+b. O–c. Cl3+d. Ca2+e. Ti

FREE Expert Solution

a. Electron configuration for B3+

B

  • atomic number = number of electrons = 5

B3+

  • lost 3 electrons 
  • number of electrons = 5 - 3 = 2

Aufbau Principle totally fill in the lowest energy orbital first
Hund’s Rule
 electron orbitals that are degenerate (same energy) are first half-filled before they are totally filled
