In the gas phase, a single water molecule has an oxygen atom surrounded by two hydrogens and two lone pairs, and the H 2 O geometry is simply described as bent without considering the nonbonded lone pairs. The protection is based on new technology with a double casing that minimises resonance in the holder casing. Interpretation: The given each ion’s nominal mass value has to be calcualted. Under the framework of valence bond theory, resonance is an extension of the idea that the bonding in a chemical species can be described by a Lewis structure. Magnetic Resonance Imaging (MRI) MRI looks at protons of water molecules to visualise soft tissues rather than dense bones; different regions are distinguished by the mobility of water molecules.
