What is the difference between atomic radii and ionic radii?
Atomic radii refer to the size of an atom, measured as the distance from the center of the nucleus to the outer electron shell. Ionic radii, on the other hand, refer to the size of an ion, which can be larger (anions) or smaller (cations) than the corresponding atom due to the gain or loss of electrons.
What is meant by ionic radii?
Ionic radii refer to the size of an ion, typically measured as the distance between the nucleus and the outermost electron shell. The size of an ion is influenced by the number of electrons and protons it contains, with cations being smaller than their parent atoms due to the loss of electrons, and anions being larger due to the gain of electrons. Ionic radii are important in determining the crystal structure and properties of compounds.
What general statement can be made regarding the ionic radii of cations having the same number of electrons but a different number of protons?
Cations with the same number of electrons but a higher number of protons will have smaller ionic radii compared to cations with fewer protons. This is because the increased positive charge in the nucleus results in greater attraction to the surrounding electrons, leading to a more compact electron cloud.
How do the ionic radii vary within a group of metals?
In a group of metals, ionic radii tend to increase as you move down the group. This is because the outermost electron shell becomes farther from the nucleus as you move down the group, leading to larger atomic sizes and therefore larger ionic radii.
How do the ionic radii vary within a group of metals how do they vary within a group of nonmetals?
Within a group of metals, the ionic radii generally increase as you move down the group due to the addition of higher energy levels. Within a group of nonmetals, the ionic radii also increase as you move down the group due to the addition of higher energy levels, but they are typically smaller compared to metal ions of the same period.

What happens to the atomic radii of the elements as a group is descended?
As we descend down the group, the atomic radii increases. This is because the number of shells increases.

In a group of metals, ionic radii tend to increase as you move down the group. This is because the outermost electron shell becomes farther from the nucleus as you move down the group, leading to larger atomic sizes and therefore larger ionic radii.
What is the relationship between the atomic numbers and ionic radii of the elements in the group 3A?
I think that the ionic radii decrease
In the alkaline-earth group atoms with the smallest radii?
Atoms with the smallest radii in the alkaline-earth group are found at the top of the group, such as beryllium. This is because as you move down the group, additional electron shells are added, increasing the atomic radius.
Largest atomc radii?
the element futher down a group
