Because each hydrogen atom can form a hydrogen bond to an oxygen atom in another water molecule and each oxygen atom has two nonbonding electron pairs, each water molecule can form a maximum of four hydrogen bonds to four other water molecules. The result is a tetrahedral cluster of water molecules around the central water molecule. :)
Max no of hydrogen bonds in ice are four but in water they are three.

yes
Water is less dense as a solid than as a liquid. This unusual property of water is due to hydrogen bonds. As water freezes, each molecule forms stable hydrogen bonds with its neighbors, holding them at "arm's length" and creating a three dimensional crystal. In Ice Hydrogen bonds are stable In liquid water hydrogen bonds constantly break and reform.
Ionic bonds are far stronger than hydrogen bonds. Ice is held together by hydrogen bonds, and table salt, which is sodium chloride (NaCl), is held together by ionic bonds. You can hammer on ice and break the hydrogen bonds holding it together with relative ease. But you can hammer all day on salt, turn it to a white powder, and not break the sodium-chlorine bonds (those ionic bonds) in any molecules of salt by doing so.
No. they contain covalent bond and hydrogen bond

No, because ice does not contain ionic bonds. It contains polar covalent and hydrogen bonds. The hydrogen bonds force the molecules to arrange into a hexagonal crystal structure. The leaves spaces that cause the ice to expand, thus decreasing its density and allowing it to float in water.

In ice, each molecule of water is hydrogen bonded to four other water molecules, forming a hexagonal crystal lattice. This structure causes the ice to increase in volume and become less dense when it freezes.
Hydrogen bonds have more characteristics of a covalent bond than an ionic bond.
Because in water hydrogen bonding is not permanent due to random motion where as in ice it is permanent also in ice k.e.is also lower
