Exceptions to atomic radii trend
WebThe atomic radii of elements of a particular series decrease with an increase in atomic number, but this decrease in atomic radii becomes small after midway. For example, for the elements of the first transition series, the atomic radii decrease gradually from scandium to chromium, but from chromium to copper, it remains practically constant. WebAtomic size does not change consistently within a period for transition metals. The size decreases as the effective nuclear charge (Zeff) decreases. The atomic radius of main-group elements decreases across a period. Atomic radii generally increase as n increases. Atomic size does not change consistently within a period for transition metals.

WebDec 4, 2024 · Atomic radius is the distance from the nucleus of an atom to its outermost shell or electron. It has different values for different atoms depending on their sizes. However, atomic radius trends vary with periods and groups in the periodic table.

Although there are some reversals in the trend (e.g., see Po in the bottom row), atoms generally get smaller as you go across the periodic table and larger as you go down any one column. Numbers are the radii in pm. Example 3.13. 1: Atomic Radii
