15 Questions
Why does the ionic radius vary unlike the atomic radius?
Due to the number of surrounding ions or atoms bonded to it
How does an increase in spin affect the ionic radius?
Increases the ionic radius by widening the electron cloud
What happens to an ion's ionic radius as it grows in positive charge?
Decreases
How do the charges of other ions or atomic nuclei affect the electron cloud around a central ion?
Influence it and decrease its tightness
What contributes to the increase in ionic radius with an increase in negative charge?
Gaining electrons
What defines the atomic radius of an atom?
The size of the electron cloud
How does an atom's radius change when it becomes an ion?
It depends on whether it becomes a cation or anion
What term describes the change in size of an atom when it gains or loses an outermost electron?
Ionic radius
Which subatomic particle causes a change in the charge of an atom when gained or lost?
Electron
How are atoms with different numbers of subatomic particles characterized?
By their sizes
In an isoelectronic series of ions, why do different ions have different ionic radii?
Because of the differing number of protons in the ions
How does increasing electronegativity affect the atomic radius of an atom?
It decreases the atomic radius of the atom
What factor primarily influences an element's electronegativity?
Atomic radius
How does ionization energy relate to an atom's tendency to lose electrons?
Higher ionization energy leads to a lower tendency to lose electrons
What trend is observed in the ionic radius of atoms as you move down a group on the periodic table?
Ionic radius increases
Learn about the concept of ionic radius, which is the size of ions formed when an atom gains or loses electrons. Discover how the ionic radius of an element can vary based on whether it becomes a cation (positive ion) or an anion (negative ion).
