The meaning of PLATINUM METAL is any of the six precious metallic elements including platinum and elements resembling it in chemical and physical properties that belong to group VIII of the periodic table and are often subdivided into two triads one of w
Ans.Alkali metals have a single electron on their outer shell, while all the noble gases (the Group 8 elements in the periodic table including helium, neon, argon) have a full valence band with no unpaired electron to cause a reaction with other molecules[15]. ...

The metals comprise about two thirds of the known elements (see periodic table). Some metals, including copper, tin, iron, lead, gold, silver, and mercury, were known to the ancients; copper is probably the oldest known metal. Physical Properties Metals differ so widely in hardness, ...
The meaning of ALKALINE EARTH METAL is any of the divalent strongly basic metals of group II of the periodic table comprising beryllium, magnesium, calcium, strontium, barium, and radium —called also alkaline earth.
Metals occupy the bulk of the periodic table, while non-metallic elements can only be found on the right-hand-side of the Periodic Table of the Elements. A diagonal line drawn from boron (B) to polonium (Po) separates the metals from the nonmetals. Most elements on this line are metallo...
which are characterised in that the metals in the form of compounds having the general formula (Me)n(halogen)m(base)p, where Me, halogen, n, m, p have the meaning specified in Claim 1, are dissolved in an organic base, a base hydrohalide, an organic solvent and/or hydrohalide mixture...
The periodic table is a chart that shows how chemical elements are related to one another. More than 40 elements, all metals, fall within the transition metal range. Silver is also classified as a precious metal. Precious metals are not very abundant in the Earth's crust. They are ...
The general composition and the functions of the components of an electroless bath are given in Table 4. These baths are used at high temperatures to obtain a good deposition rate. The principle parameters controlling the composition of coatings from electroless baths are the concentrations of the ...
