Why does atomic radius increase down the group? Periodic Properties: The periodic table categorizes the elements according to their properties and atomic number (number of protons or electrons). Along the period (rows), the atomic number increases. Down the group (columns), chemical properties lik...
Atomic radius generally decreases from left to right across a period. This is because within a period, the outer electrons are present in the same valence shell and the atomic number increases from left to right across a period, resulting in an increased
Down the group atomic number increases with increase in atomic number. As we move down the group a new shell is added, which means the distance between nucleus and valence shell increases down the group. Hence, when we move down the group atomic radius increases. ...

Moving down a group, period numbers increase. Therefore, the number of electron orbitals surrounding the nuclei increase, resulting in a larger atom; i.e., a larger atomic radius. What is ionic trend? Ionic trend is in reference to the trend in ionic radii sizes throughout the ...

Which atom or ion has the smallest radius? Nb, Zn, Si Why does the size of atoms increase going down a group on the periodic table? Why are cations always smaller than the atoms from which they are formed? Put the ionic radii of N3-, O2-, F-...
Atomic Size & Atomic Radius - Atomic Size is the distance between the center of the nucleus and the outermost shell of electrons is called the atomic radius. Atomic radii can be measured by measuring the distance between the nuclei of atoms in a metal. T
