What Elements that don't fit the pattern?

Answer 1

In the Periodic Table, elements that don't fit the expected patterns are often referred to as anomalies. For example, transition metals like chromium and copper exhibit irregular electron configurations, where instead of following the expected order, they promote electrons to achieve greater stability. Additionally, elements like hydrogen and helium, while located in the first two spots of the table, do not neatly fit into the categories of metals, nonmetals, or metalloids. These anomalies showcase the complexity and diversity of elemental properties.
