The outermost shell of an atom can accommodate a maximum of 8 electrons.
Valence electrons are electrons present in the outermost shell of an atom, responsible for the atom’s chemical properties and bonding behavior.
Bohr’s model introduced the concept of quantized energy levels and laid the groundwork for modern quantum mechanics, revolutionizing our understanding of atomic behavior.
Bohr’s model proposes that only specific orbits with quantized energy levels are stable for electrons, explaining the stability of atoms.
