Hydrogen bonds are predominantly electrostatic interactions between a weakly acidic donor group and an acceptor atom that bears a lone pair of electrons. Hydrogen bonds are categorized as weak bonds. Hydrogen bonds are usually represented as D-H . . . A, where D-H is a weakly acidic "donor group" such as N-H or O-H, and A is a lone-pair bearing and thus weakly basic "acceptor atom" such as N or O.In biological systems, hydrogen bonds have association energies in the range -12 to -30 kJ mol-1, are much more directional than van der Waals forces although less than covalent bonds. The distance of D . . . A is normally in the range 2.7 to 3.1 angstroms.

The electrons (especially the valence electrons)
Water molecules has the property of being a dipole, which practically means the oxygen atom has a greater attraction of the electrons that the hydrogen atoms. This results in making the oxygen atom fairly negativly charged, while the hydrogen fairly positive. This gives the water molecule one positive end, and one negativ end, and the ability to bind up with themselves, (+)end of one molecule to (-)end of another.We call these bonds Hydrogen bonds.
The central atom P is bonded to the five chlorine atoms by five single covalent bonds. So, the total number of single bonds is 5. The hybridization must be among one s orbital, three p orbitals and one d orbital each of which has a half filled orbital to share with the half filled orbital of each chlorine atom. So the hybridization can be written as sp3d. 1s, 3p and 1 d, a total of 5. An easy way to find the hybridization is to count the number of bonds including the unshared electrons around the central atom. For double or triple bond count only one. If the total number of bonds including the number of unshared electron pairs is 6, then the hybridization will be sp3d2, a total of 6.
A model of the atom is a 3-D structure of the atom's structure.
The electron configuration for this atom is 1s22s22p63s23p64s23d64s2. There are 6 d electrons.

Atom bomb. Get it? Atom :D
In icl3 central atom is iodine and its valency is 7 out of 7 electrons 3 electrons are in chemical bonding so 2 lone pairs are there. Hybridization = number of sigma bonds + number of lone pairs = 3 sigma bonds + 2 lone pairs = 5 = sp3d ( 1 s + 3 P + 1 d = 5 ).
