Atomic radius down group 2 - Creative Chemistry
WebThe atomic radius of the elements increases as we go from right to left across a period and as we go down the periods in a group. The increase in atomic size going down a column is also due to electron shielding, but the situation is more complex because the principal quantum number n is not constant. WebFeb 5, 2024 · Why does atomic radius generally increase down a group on the periodic table? a.
