Identify the group and period for each of the following. Refer to the periodic table. Label each as a metal, nonmetal, or metalloid. (a) C (b) Po (c) Cr (d) Mg (e) B Properties of Metals, Non-Metals & ...
A strong clue in metal identification is color. It can differentiate precious metals, magnesium, aluminum, brass, and copper. If there are signs of oxidation, remove it via scraping to reveal the color of the unoxidized surface. Scraping aids in the identification of copper, magnesium, and lea...
The acquisition of photosynthesis is a fundamental step in the evolution of eukaryotes. However, few phototrophic organisms are unambiguously recognized in the Precambrian record. The in situ detection of metabolic byproducts in individual microfossils i
The transition from linear production towards a circular agro-food system is an important step towards increasing Europe’s sustainability. This requires re-designing the food production systems, which inevitably comes with challenges as regards controll
