There might be others but these are the 5 most essential and unusual ones.
when water freezes, it expands. Most elements contract when frozen.
Hydrogen bonding between water molecules is responsible for many of water's unusual physical properties, such as high surface tension, cohesion, and adhesion. This bonding is a result of the attraction between the partially positive hydrogen atoms of one water molecule and the partially negative oxygen atom of another water molecule.
After my opinion nitrogen hasn't any unusual and very specific properties.

Water is considered an unusual molecule because of its unique properties, such as high surface tension, high specific heat capacity, and solid form (ice) being less dense than its liquid form. These properties are due to hydrogen bonding between water molecules, which gives water its special characteristics and behavior unlike other liquids.
Liquid water is denser than ice.,Ice floats on top of liquid water. apex mike asencio
Mostly from the fact that there is strong hydrogen bonding between the molecules. This, for instance, gives water much higher melting and boiling points than we'd otherwise expect for such small molecules.
It is chemically inert gas
It is not magnetic. hello everybody
The unusual properties of water molecules are due to its polar nature and hydrogen bonding. Water's bent shape causes it to have an uneven distribution of charge, resulting in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms. This polarity allows water molecules to attract each other through hydrogen bonding, which contributes to its high surface tension, specific heat capacity, and ability to dissolve a wide range of substances.
some special properties for water are lakes, water parks, bathtub, toilets, refrigeraters, and the human body itself because we contain 99% water. many other objects have water.
