Key Concepts

Effective Nuclear Charge

Effective nuclear charge is the net positive charge experienced by an electron after accounting for the shielding effect of inner electrons. An increase in effective nuclear charge generally leads to a stronger attraction between the nucleus and the electrons, thereby increasing the ionization energy required to remove an electron from an atom.

Atomic Size (Atomic Radius)

Atomic size, or atomic radius, is a measure of the distance from the nucleus to the outermost electron cloud in an atom. A smaller atomic radius typically means that valence electrons are held more tightly by the nucleus due to a higher effective nuclear charge, which results in a higher energy requirement to remove an electron (ionization energy). Conversely, larger atoms with a larger atomic radius have valence electrons that are less strongly attracted, leading to lower ionization energies.

Ionization Energy

Ionization energy is the energy required to remove an electron from an atom in its gaseous state. The first ionization energy refers to the removal of the first electron. It is influenced by factors such as atomic size, effective nuclear charge, and electron shielding, all of which determine how strongly electrons are held by the nucleus.

Periodic Trends

Periodic trends describe the predictable patterns in properties such as atomic size and ionization energy across the periodic table. Typically, ionization energy increases across a period from left to right due to an increase in effective nuclear charge and decreases down a group because the increasing size and electron shielding makes it easier to remove an electron.
