Platinum is a naturally occurring chemical element that is actually about 30 times rarer than gold, according to Jenny Luker, president of Platinum Guild International USA (PGI), a marketing organization for the platinum jewelry industry.
Mercury, in its many forms, is not an element to mess with. In its pure form, mercury is an element -- symbol Hg on the periodic table, metallic, atomic number 80. It's a silvery substance that's liquid at room temperature, and it's naturally occurring. Some estimates put the amount...
and in the molecular cases that the molecules aren’t torn apart by the force of the electric field, the material functions as an insulator; it doesn’t support a sustained flow of charge when an electric field is applied, though it does effectively permit some charge...

A molecular formula describes which atoms are present in a molecule. The subscript number found after the elemental symbol indicates the number of atoms present for each element in the molecule. Answer and Explanation: The molecular formula of ammonium nitrate is NH4NO3. The molecular formula indicat...
Niobium is a useful microalloying element for steel, inside which it forms Nb carbide and Nb nitride. These compounds enhance the grain refining and retard recrystallization and precipitation hardening. These effects subsequently improve the toughness, strength, formability, and weldability. Within micro ...
Selenium is a chemical element and has the chemical symbol Se. It has anatomic number34. Selenium is a nonmetal and more rarely a metalloid. The properties of selenium intermediate between the elements above and below selenium in the periodic table i.e., sulfur and tellurium. Selenium has simi...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
