Key Concepts

Metallic Character

Metallic character refers to the tendency of an element to lose electrons and exhibit properties typical of metals, such as conductivity and malleability. In the periodic table, elements on the left side of a period tend to be more metallic, as they have lower ionization energies and larger atomic radii compared to elements on the right.

Electron Configuration and Unpaired Electrons

Electron configuration describes the distribution of electrons in an atom's orbitals. Unpaired electrons are electrons that occupy orbitals by themselves, without a partner, which influences the magnetic properties and reactivity of the element. The number of unpaired electrons can be determined by the specific arrangement of electrons in the atom's orbitals.

Ionization Energy

Ionization energy is the energy required to remove an electron from a neutral atom in the gaseous state. It generally increases across a period due to increasing effective nuclear charge, which more strongly attracts electrons, making them harder to remove.

Atomic Radius

Atomic radius is a measure of the size of an atom, often defined as the distance from the nucleus to the outer edge of the electron cloud. Within a period, atomic radius typically decreases from left to right because of the increasing effective nuclear charge that pulls electrons closer to the nucleus.
