This dome-like shape forms due to the water molecules' cohesive properties, or their tendency to stick to one another. ... Water molecules at the surface (at the water-air interface) will form hydrogen bonds with their neighbors, just like water molecules deeper within the liquid.
The stability of atoms depends on whether or not their outer-most shell is filled with electrons. If the outer shell is filled, the atom is stable. ... In ionic bonds, atoms donate or receive electrons to achieve stability. In covalent bonds, atoms share electrons to achieve stability.
Thus, ionic bonds increase the stability of atoms
The solid is ice because it has london disperson forces due to electron revolving around nucleus in atom of hydrogen and oxygen
It also has dipole-dipole attraction due to differnce in electronegativity among hydrogen and oxygen atom
It also has hydrogen bonding between oxygen and hydrogen
