It has a low melting point (27 o C, 81 o F) and, if enough of it could be accumulated, it would be liquid in a warm room. Praseodymium is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. Our Periodic Element comparison tool allows you to compare Periodic Elements properties side by side for all 118 elements | SchoolMyKids Interactive Dynamic Periodic Table, Periodic Table Element Comparison tool, Element Property trends Adding a heat will convert the solid into a liquid with no temperature change. The chemical symbol for Lanthanum is La. Actinium gave the name to the actinide series, a group of 15 similar elements between actinium and lawrencium in the periodic table. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion. Emptiness In Me.

Mercury is commonly known as quicksilver and was formerly named hydrargyrum. It readily forms hard, stable carbides in alloys, and for this reason most of world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. Francium - Boiling Point. Group Name: Alkali Metal. The chemical symbol for Zirconium is Zr. There are over 100 different borate minerals, but the most common are: borax, kernite, ulexite etc. In general, melting is a phase change of a substance from the solid to the liquid phase.
