Spiral form of the periodic table.Note that the standard form of the periodic table usually has hydrogen (H) located in Group 1, as shown here, despite it being a gas while the other compounds are metals. The r

The great advantage of that solution is to make visible how important are the subrings, and not the rings, of the electronics layers. That's why we can call this representation "the table of subrings". "They seem to be responsible of element chemistry. However, most of time the atom ...
colours when introduced into the flame. This is because oflow ionisation energyvalues, the electrons can be easily excited by absorbing energy from flame. When the excited electrons come to original levels, they emit radiations which fall in visible region and are, therefore, coloured. ...
Caesium is also gold coloured. The gold colour seems related to relativistic effects of the outermost gold orbitals. Small amounts of other metals alloyed with gold change the colour as well as mechanical properties such as hardness. White gold for jewellery is formed by mixing palladium, ...
The coloured circles represent the FWHM areas of Gaussian components used to model the intensity distribution at each epoch, with colours matching those in Fig. 3b. Extended Data Fig. 4 REDFIT periodograms. a, For optical flux densities. b, For γ-ray fluxes. c, For degree of polarization....

Why couldn't Mendeleev organize the entire table during his research? Why are alkali metals more reactive than alkaline-earth metals? Describe why most of the compounds formed by transition elements are coloured. How do we know that matter is composed of atoms?
