Study Notes

The Periodic Table and Element Properties

The periodic table is divided into 18 groups, each with a corresponding number.
Valence electrons in each group are determined by the group number, with specific patterns.
Reactivity of elements is determined by the number of valence electrons and their stability.
Group 1 and 2 elements are the most reactive metals, while Groups 16 and 17 are the most reactive nonmetals.
Elements in the same group have similar chemical behaviors due to the same number of valence electrons.
Group 1 contains alkali metals, which are very reactive and have 1 valence electron.
Group 2 contains alkaline-earth metals, which are also reactive and have 2 valence electrons.
Transition metals, found in Groups 3-12, are less reactive and have higher density and conductivity.
Lanthanide and Actinide series are placed below the main table and contain very reactive and unstable elements.
Metalloids, found in Groups 13-16, have characteristics of both metals and nonmetals.
Halogens in Group 17 are very reactive nonmetals and never found uncombined in nature.
Noble gases in Group 18 are nonreactive and have full outer energy levels.
