Mendeleev Periodic Table

Mendeleev's Periodic Table of Elements (1869) is the canonical scientific classification visual — an 18-column grid-tabular structure organizing 118 elements by group, period, and classification, color-coded into chemical families. Born in St. Petersburg in *Zhurnal Russkogo Khimicheskogo Obshchestva*, it predicted elements not yet discovered.

The aesthetic is warm cream chemistry-paper, deep-black ink, saturated group-color-coded cells (alkali red, halogen green, noble-gas blue, transition yellow), and clean modernist sans-serif typography. It feels like a precise scientific chart: rigorous grid, tight letter-spacing, monospaced element symbols, atomic numbers indexed at every cell.

门捷列夫元素周期表 (1869) 是科学分类视觉的经典之作 —— 一张以 18 列网格组织 118 种元素的图表，按族、周期与类别归类，并以化学家族色彩编码。它诞生于俄罗斯圣彼得堡，发表在《俄罗斯化学学会杂志》上，甚至预言了当时尚未发现的元素，奠定了现代化学的基石。

审美调性是温润的化学纸米黄、漆黑的墨迹与饱和的族系配色 —— 碱金属的赤红、卤素的青绿、惰性气体的深蓝、过渡金属的明黄，配以干净的现代无衬线字体。整体如一张严谨的科学图表：网格精确、字距紧凑、元素符号采用等宽字、原子序数标注于每格之中，散发出门捷列夫式的科学秩序之美。
