Platinum also may be found as a byproduct of processing other metals like nickel and copper. Most platinum is derived from a mineral called cooperite, also known as platinum sulfide. Platinum is even found in outer space. "Platinum has also been discovered in heavy concentrations in meteorites...
You need to alloy them with a trace of copper or some other metal to make them durable enough for coins or jewelry. Not so with rhenium, iridium, and rhodium. Though rhenium is the hardest and boasts the highest melting point (3186°C or 5767°F), iridium isn’t far behind in those...
When Gallium is added to certain metals it causes them to become brittle. Gallium has one of the largest ranges in which it is a liquid when compared to other metals.

What is Arsenic? Arsenic, a chemical element placed in the nitrogen group of the periodic table that exists in both the gray and yellow crystalline forms. Arsenic is present in three allotropic forms- black, yellow and gray. A silver-gray and brittle crystalline solid are the stable forms. ...
Atomic radius decreases across a period on the periodic table because, when moving from left to right across a row, there are more electrons in the valence shell and more protons in the nucleus. These additional protons and electrons increase the electrostatic attraction between the nucleus and th...
In general, the ionization energy increases moving up a group and moving left to the right across a period. Moreover: Ionization energyis lowest for the alkali metals, which have a single electron outside a closed shell. Ionization energyincreases across a row on the periodic maximum for the...
(the second longest period) of the periodic table. Tungsten is mainly a hexavalent cation in nature, and its ionic radius is 0.68×10-10m. Because W6+ has a small ion radius, high electricity price, strong polarization ability, and is easy to form complex anions, tungsten is mainly in ...
What color are metals on the periodic table? Element Families or Groups: Most of the elements on the period table of elements are classified as metals. The periodic table of elements groups the elements into different families based on their characteristics. There are several different families of...
