The 70 pages that link to Valence electron, each with the reason it gives.

• Valence shellBroader topic: These are the individual particles that make the shell chemically consequential.

• Bent molecular geometryRelated: Valence electrons determine how many bonds and lone pairs surround the central atom.

• NonmetalRelated: The number and behavior of valence electrons help determine nonmetal reactivity and bonding.

• PnictogenRelated: Pnictogens generally have five valence electrons, shaping their bonding patterns.

• Polar covalent bondBroader topic: Covalent bonds share valence electrons between bonded atoms.

• Post-transition metalRelated: The outer s and p electrons govern much of these elements’ chemistry.

• CaesiumRelated: Caesium’s lone valence electron drives its characteristic +1 chemistry.

• Main-group elementRelated: Main-group chemistry is largely governed by the number of valence electrons.

• Triple bondRelated: The three shared pairs are made from valence electrons.

• Boron groupRelated: Each group 13 element has three valence electrons.

• Carbon groupBroader topic: Each carbon-group element has four electrons available in its outer shell.

• Period 3 elementRelated: The number of outer-shell electrons increases across Period 3 and shapes its chemistry.

• Period 5 elementRelated: Valence-electron patterns connect the row’s position to its chemical behavior.

• Arrow pushingRelated: Curved arrows track valence electrons as they change bonding or remain as lone pairs.

• Electron countingBroader topic: Electron counting begins by identifying which electrons can enter bonds.

• Period 2 elementRelated: The number of outer-shell electrons generally increases from lithium to neon.

• Atomic and molecular structureRelated: Valence electrons largely determine which molecular structures atoms can form.

• Lewis acids and basesNarrower topic: Lewis acid–base behavior tracks the availability and movement of valence electrons.

• Orbital hybridisationRelated: Hybridisation models the orbitals associated with an atom’s bonding electrons.

• Valence and conduction bandsBroader topic: Such electrons form many of the occupied states in solids.
