a bivalent and trivalent metallic element of the rare earth group.
a white metallic element that burns with a brilliant light; the fifth most abundant element in the earth's crust; an important component of most plants and animals.
These fragments were then analysed to test for particular isotopes, or forms, of the metallic element strontium, which can reveal the geological region where individuals were raised.
systematic inorganic chemistry of metallic elements
We shall find it more convenient to consider first the metallic elements themselves.
A nonmetallic element, such as arsenic, that has some of the chemical properties of a metal.
a trivalent metallic element of the rare earth group; occurs with yttrium.
a silvery metallic element that is common in rare-earth minerals; used in magnesium and aluminum alloys.
a soft yellowish-white trivalent metallic element of the rare earth group; can be recovered from bastnasite or monazite by an ion-exchange process.
Radium, uranium, and thorium are radioactive metallic elements.
The technogenic sedimentation refers to the precipitation of gypsum, calcite, fluorite, as well as hydroxides, oxides and salts of some heavy metallic elements from polluted groundwater.
Niobium is the metallic element with the highest transition temperature.
a radioactive transuranic metallic element; found in trace amounts in uranium ores; a by-product of the production of plutonium.
"It is the most abundant metallic element in Earth's crust, chiefly in bauxite (its principal ore), feldspars, micas, clay minerals, and laterite. It also occurs in gemstones, such as topaz, garnet, and chrysoberyl; emery, corundum, ruby, and sapphire are crystalline aluminum oxide."
Arsenic and lead are also naturally occurring metallic elements that have varieties of USES in industry from insecticides to electronics.
an intensely radioactive metallic element that occurs in minute amounts in uranium ores.
a rare silvery (usually trivalent) metallic element; brittle at low temperatures but liquid above room temperature; occurs in trace amounts in bauxite and zinc ores.
Here is an example that shows some very, very metallic elements, groups one and two, and some non-metallic elements over here, five, six and seven.
It is a metallic element that is found in the crust of Earth.
There are about seventy metallic elements.
A hard brittle blue white multivalent metallic element and tarnishing.
Most metallic and some nonmetallic elements will emit characteristic radiations.
A soft silvery metallic element of the alkali metal group burns in air and reacts violently in water occurs in carnallite and lepidolite and pollucite.
a hard brittle blue-white multivalent metallic element; resistant to corrosion and tarnishing.
a very poisonous metallic element that has three allotropic forms; arsenic and arsenic compounds are used as herbicides and insecticides and various alloys; found in arsenopyrite and orpiment and realgar.
Nickel is a metallic element.
Curved metallic elements make up the structure of the tent and support a fabric shell that protects visitors from inclement weather.
