Question

Formation of f2 molecule on basis of overlapping of orbitals

Answer 1

[He] 2$s^{2}2 p^{5}$

since only 1 electron left to become stable so it form bond with other flourine atom

Answer 2

Formation of Fluorine molecule $(F_2)$

Explanation:

• The atomic number of Fluorine element is 9 and its electronic configuration is $1s^22s^22p_x^22p_y^22p_z^1$ which may be diagrammatically represented as given in the attachment.
• When the electronic configuration is examined, it is evident that there are seven electrons in the valence shell and one of the 2p orbitals is half-filled.
• When two fluorine atoms approach each other, the $2p_z$ orbitals of two atoms containing single electron form a covalent bond by the overlap of two half filled orbitals as shown in the attachment.
