How does the electronic configuration of an atom determine its reactivity?
Understand the Problem
The question is asking how the arrangement of electrons in an atom influences its tendency to react chemically. This involves understanding electron configuration and the concept of reactive elements.
Answer
Reactivity depends on valence electrons; full shells are inert, nearly full or empty are reactive.
The reactivity of an atom is determined by its valence electrons. Atoms with nearly full or nearly empty valence shells are highly reactive. In contrast, atoms with full valence shells are chemically inert.
Answer for screen readers
The reactivity of an atom is determined by its valence electrons. Atoms with nearly full or nearly empty valence shells are highly reactive. In contrast, atoms with full valence shells are chemically inert.
More Information
Valence electrons are crucial because they participate in forming chemical bonds. Atoms strive to achieve a stable electronic configuration, often that of the nearest noble gas.
Tips
A common mistake is to forget that not all atoms with unpaired electrons are highly reactive; context and surrounding conditions matter.
