give me graph paper first!!!!!!!!!!!!!!
When nonmetallic elements gain electrons to form ions, the additional electrons are added to higher energy levels (shells) farther from the nucleus. This increase in the size of the electron cloud leads to an increase in the ionic radii compared to the atomic radii of those elements.
The group of elements with members of the smallest atomic radii for a given period is the group of noble gases. Noble gases have the smallest atomic radii because they have a completely filled valence shell, which results in strong electron-electron repulsions and a smaller atomic size.
Atomic and ionic radii are estimated because they are not directly measurable quantities. They are theoretical values based on experimental data and mathematical models. Estimating these radii helps in understanding the chemical and physical properties of elements and compounds.
Yes, the atomic radii of d-block elements are generally smaller than p-block elements due to greater effective nuclear charge resulting from the filling of d orbitals that shield the outer electrons less effectively compared to p orbitals. This leads to stronger attraction between the nucleus and valence electrons, resulting in a smaller atomic size for d-block elements.
The effect is known as the shielding effect. It occurs because inner electron shells partially shield the outermost electrons from the attractive force of the nucleus, leading to variations in atomic radii among elements in the same group.
The ionic radii of metallic elements is smaller than its atomic radii, because the ion has less electrons. This gives it a smaller electron cloud and makes the atom smaller.
Look for a reference chart in a book or online. Look for a Periodic Table of the Elements that has the atomic radii on it.
As we descend down the group, the atomic radii increases. This is because the number of shells increases.

I think that the ionic radii decrease
group 1 elements
Elements to the right of the periodic table have smaller radii due to increased effective nuclear charge, which attracts the electrons closer to the nucleus. This results in a greater pull on the outer electrons and smaller atomic radii overall.
The group of elements with members of the smallest atomic radii for a given period is the group of noble gases. Noble gases have the smallest atomic radii because they have a completely filled valence shell, which results in strong electron-electron repulsions and a smaller atomic size.
The radii of elements generally decrease as you move from left to right across a period in the periodic table. The radii then increase as you move down a group in the periodic table. This trend is due to changes in the atomic structure of the elements.
