English: This pictorial periodic table is colorful, boring, and packed with information. In addition to the element's name, symbol, and atomic number, each element box has a drawing of one of the element's main human uses or natural occurrences.
The SEE examination is said to be scheduled in March of every year. As the new Education Act, 2016 (2073) has been implemented, the SLC examination will be taken place in Grade 12 as a national level examination whereas the examination of Grade 10 will be known as Secondary Education Examination (S.E.E).
The amounts of total mass in elements heavier than hydrogen and helium (called 'metals' by astrophysicists) remains small (few percent), so that the universe still has approximately the same composition. Stars fuse light elements to heavier ones in their cores, giving off energy in the process known as stellar nucleosynthesis.
The SLC (Class 11 and 12) and SEE (Class 10) examinations are normally scheduled from April to June each year. The examinations are conducted by the National Examination Board (NEB), located in Sanothimi, Bhaktapur, Nepal. Until 2016, SLC was the Grade 10 final examination, famously known as the "iron gate" [citation needed]. However, after ...
These elements already have images but they are not the highest quality. These elements aren't too rare, so it shouldn't be too hard to find other pictures. Google's probably the best bet here but it may also be worth asking one of Wikipedia's element photographers (a certain person comes to mind) to see if they can get a better photo. Barium ...

Antoine Lavoisier is regarded as the inventor of elemental analysis as a quantitative, experimental tool to assess the chemical composition of a compound. At the time, elemental analysis was based on the gravimetric determination of specific absorbent materials before and after selective adsorption of the combustion gases.
The Standard Model of particle physics contains 12 flavors of elementary fermions, plus their corresponding antiparticles, as well as elementary bosons that mediate the forces and the Higgs boson, which was reported on July 4, 2012, as having been likely detected by the two main experiments at the Large Hadron Collider (ATLAS and CMS).
