Question

What is the correct order of ionization energy of K, K+, Cu, Cu+

Answer 1

Explanation:

k^+,k,cu^+,cu

hope this may help u

Answer 2

The ionization energy of potassium is less than that of copper.

• The nucleus of potassium contains 19 protons while the nucleus of copper contains 29 protons.
• The electrons of copper are under the influence of a stronger nuclear pull than that of potassium.
• Furthermore, the presence of d-electrons in copper provides poor screening making nuclear force more stronger.
• So, it is more difficult to remove an electron from copper than from potassium.
