Raising the table…
A spreadsheet of 118 numbers does not look like a trend. The same grid you already know — 18 columns, f-block parked underneath — is the floor of this map. Height is the property. Color is the same cold-blue-to-hot-red Turbo scale as the 2D heatmap. Switch the control, and the mountains then move.
Read the slope, not a single tower
Electronegativity and first ionization energy both rise toward the upper right. Atomic radius does the opposite. The alkali metals are the high country, and each period shrinks as you walk right. That inversion is the whole first-year story. It is obvious here in a way a table of picometres is not.
Melting point, however, refuses that diagonal. The ridge sits in the middle of the d-block, where metallic bonding is strongest — tungsten, rhenium, carbon. Meanwhile the noble gases and the light alkali metals are a frozen basin. Density is another kind of mountain: osmium and iridium, then a long drop to the alkali metals, then a film of gases at STP that barely leave the floor.
Each property has its own vertical scale
Bars are normalized from the smallest to the largest known value of that property. So a millimetre of height in electronegativity is not a millimetre of ionization energy. The animation is there so your eye can watch one landscape become another. It is not there so you can subtract two peaks.
Gray pads are missing data, not zeros. Helium has no Pauling electronegativity in this set. Fermium through oganesson have no measured density here. Click any bar for the element page.
Questions this map answers
Why do some tiles sit as dim pads instead of towers?
Those elements have no value for the selected property in this dataset. That includes noble-gas electronegativities, many superheavy densities, and a few undocumented radii. A pad is therefore missing data, not a value of zero.
Can I compare bar heights after I switch properties?
No. Each property is stretched across its own minimum and maximum, so the landscape uses the full height of the view. Switch to see the shape of the trend. Do not read one millimetre as a unit.
Why does density look almost flat except for a few spikes?
Gases at STP are ~10³ times less dense than solids, so they collapse to a film. The ridge is close-packed heavy metals. Osmium and iridium sit at the top. That contrast is the point of the map.
Is this the same scale as the 2D heatmap on the home page?
Yes for electronegativity, ionization energy, radius, and melting point. Those maps use the same numbers and the same min–max coloring (Turbo, cold blue to hot red). Density, however, exists only on this landscape.
