Oxygen is the more electronegative so it will have a greater share of the bonding electrons and therefore a partial negative charge, O Hydrogen is less electronegative so it will have a lesser share of the bonding electrons and therefore a partial positive charge, H Since the bond has two 'poles' or 'ends' it is sometimes referred to as a dipole. F has such a strong attraction for electrons that it pulls the electron off the Na resulting in a negative charge for fluorine, F-, and a positive charge for sodium, Na+ The bond between Na+ and F- is NOT covalent since the bonding electrons are not shared between the 'atoms'

Density of Water Water is most dense at 4 degrees and as it warms, it becomes less dense due to increased molecular motion associated with temperature increases. The high heat of vaporization enables organisms to use evaporation as a cooling mechanism because each gram of water that evaporates from the surface of an organism at 25 degrees C removes 580 calories of heat

Above 0oC (evaporation), and particularly at 100oC (boiling), the intermolecular forces are weak enough for 'intact water molecules' to escape from the surface of the liquid water. In the reverse process, when ice is warmed, the intermolecular forces are weakened and at 0oC the intermolecular bonds are weakened enough to allow melting to take place

The original ionisation event in these instruments results in the formation of an "ion pair"; a positive ion and a free electron, by ion impact by the radiation on the gas molecules.

When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide.
