3 Questions
What are the electrons present in the outermost shell of an atom known as?
Valence electrons
According to the Bohr-Bury scheme, what is the maximum number of electrons that the outermost shell of an atom can accommodate?
8 electrons
What is observed for the atoms of elements that are completely filled with 8 electrons in the outermost shell?
They show little chemical activity
Study Notes
Electron Configurations
- The electrons present in the outermost shell of an atom are known as valence electrons.
Bohr-Bury Scheme
- The maximum number of electrons that the outermost shell of an atom can accommodate is 8, according to the Bohr-Bury scheme.
Fully Filled Valence Shells
- Atoms of elements that are completely filled with 8 electrons in the outermost shell are observed to be chemically inert, meaning they do not readily react with other elements.
Test your knowledge of valency and electron configuration with this quiz. Explore the arrangement of electrons in different shells and orbits, and understand the concept of valence electrons. Perfect for reinforcing understanding of the Bohr-Bury scheme and the outermost shell of an atom.
