Why exchange energy is released?
The exchange energy is the energy released when two or more electrons with the same spin exchange their positions in the degenerate orbitals of a subshell. Thus electrons are more tightly bound which gives extra stability of electrons of valence shell.
How does symmetry lead to stability?
Symmetry implies that there is equal distribution. The half filled orbitals correspond to symmetrical distribution of charge. Thus s1, p3, d5 and f7 electronic configuration would be very stable and would have low energy. This is because all the orbitals are occupied with equal number of electrons.
Why 1s orbital is spherically symmetrical?
All s orbitals are spherical in shape and have a spherical symmetry. This means that the wave function will depend on the distance from the nucleus and not on the direction.In any atom,the size of the s orbital increases as the principal quantum number of the orbital increases but its geometrical shape remains same..
What is stable configuration?
A stable electron configuration refers to an atom in which the outermost (valence) shell is complete. An unstable electron configuration refers to an atom in which the outermost (valence) shell is incomplete.
What are the two ways to achieve a stable configuration?
Elements in other groups have partially filled valence shells and gain or lose electrons to achieve a stable electron configuration. An atom may give, take, or share electrons with another atom to achieve a full valence shell, the most stable electron configuration.
What is half filled configuration?
When assigning electrons to orbitals, an electron first seeks to fill all the orbitals with similar energy (also referred to as degenerate orbitals) before pairing with another electron in a half-filled orbital. The p orbitals are half-filled; there are three electrons and three p orbitals.för 5 dagar sedan
