Nuclear charge refers to the total charge of the nucleus, which is determined by the number of protons and is a fundamental factor in influencing atomic structure and chemical behavior. It affects the attraction between the nucleus and electrons, impacting ionization energy, electron affinity, and atomic radii.

Atomic structure refers to the arrangement of subatomic particles—protons, neutrons, and electrons—within an atom, which determines its chemical properties and behavior. Understanding atomic structure is fundamental to fields like chemistry and physics, as it explains the periodic table, bonding, and the nature of matter itself.

Chemical behavior refers to the way substances interact with each other, leading to chemical reactions or changes in physical state. It is fundamentally governed by the properties of atoms and molecules, including their electron configurations and the types of bonds they can form.

Ionization energy is the amount of energy required to remove an electron from an isolated atom or ion in its gaseous state. It is a fundamental property that reveals the reactivity of elements, with higher ionization energies indicating a stronger hold on electrons and typically less reactivity.

ionization energy

Electron affinity is the energy change that occurs when an electron is added to a neutral atom in the gaseous state, indicating how strongly an atom can attract additional electrons. It generally becomes more exothermic across a period due to increasing nuclear charge and less exothermic down a group due to increased atomic radius and electron shielding.

electron affinity

Atomic radii refer to the size of an atom, typically measured from the nucleus to the outermost electron shell. It generally decreases across a period due to increased nuclear charge and increases down a group as additional electron shells are added.
