Arrange in increasing order of ionic radii li+,mg2+,k+,al3+
Answers
Ans should be K+>Li+>Mg+2>Al+3 for Mg3+and Al3+ you can just check (z/e) ratio as these two are isoelectronic species, and you must know that, Li+ is slightly greater than Mg2+ this is a experimemntal data, the reason is out of your syllabi as it includes Schrodinger's eqⁿ,well K+ has the configuration of Ar[18] which makes it larger among them as noble gases are abnormally larger than their neighbor elements due to extra stabilitu, hope it helped, mark brainliest.
Answer: In increasing order-
Al3
Mg2
li
k
Explanation:
1) Al3 - Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13.
2) Mg2- Magnesium cation is a Calculi Dissolution Agent and Osmotic Laxative. The mechanism of action of magnesium cation is as a Magnesium Ion Exchange Activity and Osmotic Activity.
3) li - Lithium (from Greek: λίθος, romanized: lithos, lit. 'stone') is a chemical element with the symbol Li and atomic number 3
4) k - Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19
