In a group the atomic size
WebFeb 23, 2016 · Atomic size INCREASES down a Group, but DECREASES across a Period. Explanation: As we go across a Period, a row, of the Periodic Table, from left to right as … WebThe atomic radius is the distance from the atomic nucleus to the outermost electron orbital in an atom. In general, the atomic radius decreases as we move from left to right in a period, and it increases when we go down a group. This is because in periods, the valence electrons are in the same outermost shell.

WebMar 16, 2024 · Atomic size is the distance from the nucleus to the valence shell. Ionization energy is the energy required to remove the most loosely held electron from a gaseous atom or ion. Ionization energy increases across a period and decreases down the family. So as the Atomic size increase so does Ionization Energy. WebFeb 7, 2024 · An atomic radius is one-half the distance between the nuclei of two atoms. Atomic radii are measured in picometers (one picometer is equal to one trillionth of a meter). Hydrogen (H) has the smallest average atomic radius at about 25 pm, while caesium (Cs) has the largest average radius at about 260 pm. What Are the Atomic Radius Trends?

WebNov 5, 2024 · As you move down an element group (column), the size of atoms increases. This is because each atom further down the column has more protons and neutrons and also gains an additional electron energy shell. As you move across an element period (row), the overall size of atoms decreases slightly.
