Are there metals far scarcer than iridium and enormously more expensive than gold — while at the same time, non-radioactive or very, very nearly so? As it happens, yes. A line of radioactive cosmetics introduced in 1930 Each element comes in varieties called isotopes whose atoms differ in...
@valleyfiah- Mercury is one of the most unique elements in the periodic table. The metal is only one of two elements that are liquid at standard temperature and pressure (stp). Mercury also has a very short temperature range between the freezing and boiling points. Mercury is the only trans...
And there are also concerns around the safety and sustainability(可持续性) of ithium batteries.Mining the metals needed for them comes with a high social and environmental cost.This has urged scientists around the world to try and develop new types of battery that can overcome theseproblems. ...

Metals usually appear in crystalline structures, while nonmetals take many different forms. Noble gases, as their name implies, appear as gasses at room temperature. All elements can form compounds, though some do so less readily than others. Similarly, every element can change state – liquid,...
Large depth of market:Again, the Emini market is so liquid that there is plenty of volume on either side of the last traded price, allowing large orders to be filled with minimum slippage (or difference from the previous traded price). ...
It is resistant to hydrochloric, nitric and sulfuric acids, in addition to many liquid metals and organic chemicals. Due to this, tantalum is widely applied in chemical equipment like heat exchangers, reaction vessels and tantalum tubes.The resistance of tantalum to chemical reactions also makes it...
it changes from solid to liquid. Sintering is different because the heating process is highly controlled. You get the enhanced properties you need without having to melt the metal. One of the great things about sintering is that you can easily make parts out of metals with high melting points...
Learn about the three most common states of matter in the universe, which are solid, liquid, and gas. Discover the properties of these states and how the particles in these states move. Related to this Question What state of matter are most nonmetals?
We also apply many synthetic organic chemicals, metals, and radioactive materials to soils that can damage ecosystems and can have serious human health effects. The clean-up of soils is among the great efforts being conducted by soil scientists around the world. Soils are... HomeThe phrase "...
