Since these dipole powers are more fragile than covalent or ionic bonds, sub-atomic solids are delicate and have generally low softening temperature. Unadulterated atomic solids are electrical covers however they can be made conductive by doping. Instances of sub-atomic solids ...
In ionic compounds, hydrogen can take the form of a negative charge (i.e., anion) where it is known as a hydride, or as a positively charged (i.e., cation) species denoted by the symbol H+. The H+ cation is simply a proton (symbol p) but its behavior in aqueous solutions and ...
