Samarium is a chemical element; it has symbol Sm and atomic number 62. It is a moderately hard silvery metal that slowly oxidizes in air. Being a typical member of the lanthanide series, samarium usually has the oxidation state +3. Compounds of samarium (II) are also known, most notably the monoxide SmO, monochalcogenides SmS, SmSe and SmTe, as ...
Rubidium, 37Rb. body-centered cubic (bcc) ( cI2) Rubidium is a chemical element; it has symbol Rb and atomic number 37. It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. [8] Rubidium is the first alkali metal in the group to have a density higher than water.
2024 in heavy metal music. Heavy metal (or simply metal) is a genre of rock music that developed in the late 1960s and early 1970s, largely in the United Kingdom and United States. [2] With roots in blues rock, psychedelic rock and acid rock, heavy metal bands developed a thick, monumental sound characterized by distorted guitars, extended ...
The dividing line between metals and nonmetals can be found, in varying configurations, on some representations of the periodic table of the elements (see mini-example, right). Elements to the lower left of the line generally display increasing metallic behaviour; elements to the upper right display increasing nonmetallic behaviour.
Chromium, a metal and sulfur, a non-metal. The periodic table can be broadly segregated into two types of elements, commonly referred to as metals and non-metals.Each of these elements have varying properties and can be found in a wide variety of places, such as bridges, buildings, roads, electric cables, cars, aircraft, mobile phones, and laptops, as well as in the oxygen we breathe and the ...
Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine .
Bromine. orthorhombic ( oS8) Bromine is a chemical element; it has symbol Br and atomic number 35. It is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine.
