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...
As described above, diatoms take up Si from their surrounding water during the formation of their silica frustules and a kinetic isotope fractionation (Box 1) occurs because the different Si isotopes have slightly different rate constants during dissolved Si uptake and polymerization (Cassarino et al...
Physical Properties: Different elements have distinct physical properties. If an element is malleable, it can be flattened into a sheet with enough repetitive pressure. If an element is ductile, it can be formed into a thin wire. Answer and Explanation: ...
4. Physical Properties: - Although they have the same chemical properties, the isotopes differ in their physical properties. This is due to the difference in mass (mass number) caused by the different number of neutrons. - 35Cl17 has 18 neutrons (35 - 17) while 37Cl17 has 20 neutrons ...
How are isotopes different from stable atoms? Explain how to determine how and if atoms have valence electrons. How do ions form ionic bonds? Which part of the atom forms chemical bonds? How are reactions related to chemical bonds? How are ionic and covalent bonds different from hydrogen bonds...
Given the recent focus on the C sequestration potential of soils21 and considering the importance of tropical forests in mitigating the global rise in atmospheric CO2 22, it is essential that we establish whether changes in plant inputs have the potential to modify the processes underlying the ...
Compared to challenges of quantifying C outputs and their depth-origin, C inputs to the soil can be represented by root-derived C and reasonably estimated using state-of-the-art tracer (e.g., C isotopes) techniques (Balesdent et al., 2018) or by root growth measurements (Raich and Nadel...
We now know that neutrinos have some very fundamental differences with other particles of the Standard Model. Firstly, except for the photon they are the only electrically neutral stable particle we know exists for sure (could dark matter be another?). This leads to the curious fact that there...
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. (c) have consecutive atomic numbers. (d) make up a period of elements.What are the e...
How can cobalt-60 and cobalt-59 be the same element? How is fluorine different from other halogens? What chemical elements make iron rust? Explain why isotopes of the same element have the same chemical properties but different physical properties. How are the isotopes of a partic...
