14 Questions
What causes the ionic radius to vary?
Spin and coordination number
Why do ionic radii increase with the number of surrounding bonds?
Influence on electron cloud by charges of other ions
How does an increase in spin affect the ionic radius?
Forces the electron cloud to widen
What happens to the ionic radius if an ion increases in positive charge?
It loses electrons and decreases its ionic radius
Why does an ion increasing in negative charge increase its atomic radius?
It gains electrons and decreases its atomic radius
What influences the tightness of the electron cloud around a central ion?
Ionic charge
Which factor determines the increase of ionic radii with an increase in spin?
Rotational flux of the ion
How does the ionic radius differ from the atomic radius?
Ionic radius decreases with increasing positive charge, while atomic radius increases with increasing negative charge.
In what scenario would an ionic radius decrease?
When the ion gains electrons.
What effect does an increase in the spin of an ion have on its ionic radius?
It increases the ionic radius.
How does the number of surrounding bonds impact the ionic radius?
Increases the ionic radius.
What causes a decrease in the tightness of the electron cloud around a central ion?
Increase in positive charge of surrounding ions.
How does an increase in coordination number affect the electron cloud around a central ion?
Loosens the electron cloud.
Which factor influences the electron cloud's tightness around a central ion?
Increase in positive charge of other ions.
Learn about how atoms can become ions by gaining or losing electrons, leading to changes in their atomic and ionic radii. Understand the concept of cations and anions and how they affect the size of an element's ions.
