Question
Suggest which of the following ions is harder.
a) zinc(II) or mercury(II)
b) potassium(I) or copper(I)
c) iron(II) or iron(III)
Answer a:
Answer b:
Answer c:
Solution
Sure, here are the answers:
Answer a: Zinc(II) is harder than Mercury(II). This is because Zinc(II) has a smaller ionic radius and higher charge density than Mercury(II), which makes it harder.
Answer b: Copper(I) is harder than Potassium(I). This is because Copper(I) has a smaller ionic radius and higher charge density than Potassium(I), which makes it harder.
Answer c: Iron(III) is harder than Iron(II). This is because Iron(III) has a smaller ionic radius and higher charge density than Iron(II), which makes it harder.
