Element 'A' and 'B' have atomic number 18 and 16 respectively.Which of these two would be more reactive any why? View Solution The elements A,B,C,D and E have atomic number 9,11,17,12 and 13 respectively. Which pair of elements belong to the same group?
The periodic table is ubiquitous within the academic discipline of chemistry and provides an extremely useful framework to classify, systematize, and compare all known elements of their chemical behaviour. For each element, the electronic configuration, atomic mass, and weight are displayed in a popup...
A known ‘volatile trend’ line is well established and has been used to explain the abundances of elements in the silicate Earth, with the general observation that the lower the condensation temperature of an element, the greater depletion in the solid Earth12. However, by comparing the ...
The microalloy elements Nb, V, and Ti all form carbonitride precipitate phases of the type M(CxN1−x), where M=microalloy element and x varies from 0 to 1 (Gladman 1997). Most carbonitrides have the “NaCl” crystal structure with the substitutional atoms occupying one sublattice and ...
Silicon’s atomic number is 14, it’s atomic symbol on the Periodic Table of Elements is Si, and it’s atomic weight (average mass of the atom) is 28.09. According to the Royal Society of Chemistry, silicon is the seventh most abundant element in the universe and the second most abundan...
While the exact composition of the core remains unknown, tighter constraints on core temperature and better connections between the solid inner core and the liquid outer core compositions will help narrow the range of potential light element compositions. Key points Constraining the light element ...
