Areas of the periodic table
Background image
The properties of the elements follow a periodic pattern.Elements in the same column have similar properties.The elements in a period show a pattern that repeats.The quantum-mechanical model explains this because the number of valence electrons and the types of orbitals they occupy are also periodic.Properties and Electron Configuration
Background image
The alkalimetals have one more electron than the previous noble gas.In their reactions, the alkali metals tend to lose one electron, resulting in the same electron configuration as a noble gas.Forming a cation with a 1+ chargeAlkali metals are very reactiveThe alkaliearth metals have two more electron than the previous noble gas.
