In a group from top to bottom atomic size
WebMar 20, 2024 · Atomic size gradually decreases from left to right across a period of elements. This is because, within a period or family of elements, all electrons are added to the same shell. Down a group, atomic radius increases. The valence electrons occupy higher levels due to the increasing quantum number (n). WebYes , atomic size increases down the group . Reason : As we move down the group , the number of shells increases in the atom , with the increase in the number of shells the atomic size increases . As , we move down the …

WebMar 22, 2024 · So, down the group (from top to bottom), the atomic size increases. So Electronegativity decreases. And across the period (from left to right), the atomic size decreases, so the Electronegativity increases. For electronegativity values of elements, visit Interactive periodic table. WebJul 3, 2024 · Ionization is at its minimum value for the alkali metal on the left side of the table and a maximum for the noble gas on the far right side of a period. The noble gas has a filled valence shell, so it resists electron removal. Ionization decreases moving top to bottom down an element group (column).
