  1. 1s2
  2. 1s22s22p5
  3. 1s22s1
  4. 1s22s22p63s23p6
  5. 1s22s22p63s23p63d24s2

Step by step solution

01

writing the electron configuration of B3+

Observing the periodic table, we can write the electron configuration as,

B3+= 1s2

02

writing the electron configuration of O-

Observing the periodic table, we can write the electron configuration as,

O- = 1s22s22p5

03

writing the electron configuration of Cl3+

Observing the periodic table, we can write the electron configuration as,

Cl3+=1s22s1

04

writing the electron configuration of Ca2+

Observing the periodic table, we can write the electron configuration as,

Ca2+=1s22s22p63s23p6

05

writing the electron configuration of Ti  

Observing the periodic table, we can write the electron configuration as,

Ti = 1s22s22p63s23p63d24s2
