Nominal Ordinal Interval Ratio Nominal The lowest measurement level you can use, from a statistical point of view, is a nominal scale. A nominal scale, as the name implies, is simply some placing of data into categories, without any order or structure.ominal Ordinal Interval Ratio Nominal The lowest measurement level you can use, from a statistical point of view, is a nominal scale.

In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond. See Fig. 3-7.
Why do most atoms form chemical bonds? By bonding the atoms with gain or lose electrons in an ionic bond or share electrons in a covalent bond to have 8 valence electrons (an octet) like the noble gases (except for H which likes 2 electrons to be like He). This makes them stable like the noble gases which lowers their potential energy.
