Increasing Order of Polarizing Power of Cationic Species
To determine the increasing order of polarizing power of the cationic species provided (K+, Ca+2, Mg+2, Be+2), we need to consider the charge/size ratio of each cation.

Charge/Size Ratio
- The polarizing power of a cation is determined by its charge/size ratio.
- A higher charge/size ratio indicates a greater polarizing power.

Sequence of Cationic Species
- K+ (Potassium ion)
- Ca+2 (Calcium ion)
- Mg+2 (Magnesium ion)
- Be+2 (Beryllium ion)

Increasing Order of Polarizing Power
- The increasing order of polarizing power of the cationic species is:
- K+ < ca+2="" />< mg+2="" />< />

Explanation
- Beryllium ion (Be+2) has the highest charge/size ratio among the cationic species provided, making it the most polarizing.
- Potassium ion (K+) has the lowest charge/size ratio, indicating the lowest polarizing power among the cations listed.
- Therefore, the correct sequence in increasing order of polarizing power is Be+2 < mg+2="" />< ca+2="" />< k+.="" />
