In a similar way, xenon isotopic ratios such as 129 Xe/ 130 Xe and 136 Xe/ 130 Xe are a powerful tool for understanding planetary differentiation and early outgassing. [28] For example, the atmosphere of Mars shows a xenon abundance similar to that of Earth (0.08 parts per million [ 97 ] ) but Mars shows a greater abundance of 129 Xe than the ...

The copper content typically varies from 60 to 90 percent. (Monel is a nickel–copper alloy that contains a minimum of 52 percent nickel.)
Copper is emerging as the next indispensable industrial commodity, mirroring oil's rise in earlier decades, a top commodities analyst said. This time around, new forces in the economy, namely the ...
Pre-1992 British pennies were made of 97% copper; but as of 2008, based on the price of copper, the value of a penny from this period is 1.5 new-pence. Modern British pennies are now made of copper-plated steel. Cupronickel, a base metal alloy with varying proportions of copper and nickel, was introduced as a cheaper alternative for silver in ...
