The image shown above depicts how additional neutrons create different isotopes of hydrogen. Isotopes have the same number of electrons, and therefore have the same chemical properties. There is, however, a difference in the element’s physical properties due to their difference in mass (number of...
Radioactive isotopes differ from isotopes in that radioactive isotopes are unstable and undergo radioactive decay. If the ratio of neutrons to...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it risk-free Ask a question Our experts can answer your tough ...

A compound known as cubic boron nitride has a similar structure to that of a diamond. What properties do you expect it to have?Elements in the same group in the periodic table (a) have similar chemical properties. (b) are called isotopes. ...
Instead, biological, physical and chemical fractionation of SOC indicated gains in accessible SOC with litter addition but a decline in intermediate mineral-associated SOC, which is consistent with our second (alternative) hypothesis. Hence, we propose that increased incorporation of new litter-derived ...
It should be mentioned that the contamination of tea leaves mainly occurs due to the chemical compositions and physicochemical properties of the soils in which plants grow, and the plant’s metabolism as well [25,26,27]. Obtaining knowledge on the absorption and accumulation levels of heavy ...
Furthermore, two main gradients of physical and chemical properties were identified: a gradient of increasing soil TOC, TN, and POXC values and a gradient of increasing pH and CEC values. The data were transformed using f(x) = log10(x) where necessary [41]. In addition, GLU and ARYL ...

Substances which can serve as useful detectable labels are well known in the art and include radioactive isotopes, fluorescent molecules, chemiluminescent molecules, chromophores, as well as ligands such as biotin and haptens which, while not directly detectable, can be readily detected by a ...
