Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Definition of Contraction**: - Contraction refers to the decrease in size of the atomic or ionic radii of elements as we move across a period in the periodic table. 2. **Lanthanide Contraction**: - The lanthanide series consists of elements from Lanthanum (La, atomic number 57) to Lutetium (Lu, atomic number 71). - The contraction occurs due to the filling of the 4f subshell. ...
