Periodic Table Concepts and Electron Configuration

These flashcards cover key concepts from the periodic table, electron configurations, and associated trends in chemistry.

Periodic Law

The periodic law states that the properties of elements recur in a repeating pattern when arranged according to increasing atomic number.

Electron Configuration

The arrangement of electrons in an atom which can be represented in shorthand using the nearest noble gas.

Valence Electrons

The outermost electrons of an atom that are involved in chemical reactions.

Ionization Energy

The amount of energy required to remove an electron from an atom in the gaseous state.

Atomic Radius

The size of an atom, which decreases from left to right across a period and increases from top to bottom in a group.

Alkali Metals

The elements in Group IA/1, known for having one valence electron and being highly reactive.

Noble Gases

The inert gases in Group VIIIA/18 that have complete valence electron shells.

Ionic Charge

The charge on an ion, which is determined by the number of valence electrons lost or gained.

Isoelectronic Series

Atoms or ions that have the same electron configuration.

Electron Dot Formula

A representation of an atom showing its valence electrons as dots around the element's symbol.
