Key Concepts

Periodic Trends

Periodic trends are patterns observed in the properties of elements as one moves across a period or down a group in the periodic table. These trends include changes in atomic radius, electronegativity, and ionization energy. In the context of atomic size, atomic radii generally decrease across a period and increase down a group, guiding the selection of larger atoms in a set of elements.

Atomic Radius

Atomic radius is a measure of the size of an atom, typically defined as the distance from the nucleus to the outermost electron cloud. It is influenced by the number of electron shells (which increases the size down a group) and by the effective nuclear charge (which can pull the electrons closer when there are more protons relative to electrons).
