Answer to Question #1295 Submitted to "Ask the Experts"Category: Radiation Basics — Elements The following question was answered by an expert in the appropriate field: Q
How many elements on the periodic table are solids at room temperature?
A
Some periodic tables show color-coded symbols for the elements according to their state of condensation at room temperature. One which I have, published by Sargent-Welch Scientific Company, shows solids in black, liquids in blue, and gases in red. Synthetic elements are shown in outline. On my chart I count 11 gases, 5 liquids (Ga, Br, Cs, Hg, Fr) and 2 synthetics (Tc, Pm) among the first 92 elements. This leaves a total of 74 solids among the 90 naturally occuring elements at room temperature. Then, in addition, there are the solid transuranic elements.
