A color-coded periodic table of the elements displays each element's symbol and atomic number, with categories such as alkali metals, noble gases, halogens, transition metals, and actinoid elements distinguished by different background colors.

Diagram of an aluminum chloride (Al2Cl6) molecule showing two blue aluminum atoms each bonded to multiple yellow chlorine atoms, illustrating the structure of this inorganic compound.

Two molecular diagrams show a central orange atom labeled M bonded to surrounding atoms. The left structure has four yellow halogen atoms labeled X and two red donor atoms labeled D attached to M. The right structure, enclosed in brackets, shows M bonded to six yellow halogen atoms labeled X, representing a different coordination environment.

A graph plots the melting points in kelvins of group 13 elements-gallium, indium, thallium, and aluminum-against their periodic table row, with an estimated value shown for nihonium (Nh) extrapolated as a red dot.
