  1. Water, H2O, is composed of 3 atoms which are covalently bonded
  2. Water is a polar molecule, which means it has an overall dipole as a result of opposing charges
  3. According to water's neighbouring molecules in the Periodic Table of Elements, ice should melt somewhere around -1000*C, but actually melts at 0*C
  4. n almost all other materials, the solid is denser than the liquid

Water may seem like a very simple molecule, but in fact it has many anomalies. These make it hard to predict the properties of water. This essay will explain just a few of its unusual properties.

[...] This is why ice is able to float on water. References; Structure of a water molecule- www.ausetute.com.au/shapemol.html Polar molecules- www.biology-online.org/dictionary/polar_molecule Anomalous properties of water- www.hcli.com/anomalous-and-unique- properties-of-water/ Polarity and structure of molecules- OCR AS Chemistry (Heinemann) repel each other as well as the lone pairs of electrons, and as lone pair- lone pair repulsion is greater than lone pair-bonding pair or bonding pair- bonding pair repulsion, the lone pairs push the bonding pairs of electrons close together. This results in the molecule having a bent tetrahedral shape lone pairs slight negative charge around the oxygen atom. [...]


[...] These make it hard to predict the properties of water. This essay will explain just a few of its unusual properties. Water, H2O, is composed of 3 atoms which are covalently bonded- 2 atoms of hydrogen and 1 atom of oxygen. The central atom is oxygen, which has 6 electrons in its outer shell, otherwise known as valence electrons of these electrons are used to form bonding pairs with hydrogen, forming 2 covalent bonds (as one pair is used from the hydrogen) lone pairs of electrons are formed as 4 of oxygen's valence electrons are not used for bonding.
