In the building-up principle,Zelectrons(for a neutral atom of an element ofatomic numberZ) are placed in succession into an array of hydrogen-like atomic orbitals in such a way as to achieve the lowest possible total energy. Thus, to account for the structure of aheliumatom (for whichZ=...
Following Rutherford, James Chadwick in 1932 discovered the presence of an uncharged portion of the nucleus called the neutron. These developments led to the modern day structure of the atom. Namely, a nucleus containing protons/neutrons representing the bulk of the atoms mass with electrons ...

IN our note on the crystal structure of krypton in NATURE of June 14, p. 889, we gave the ratios of the distance of nearest neighbours in the crystal lattice to the atomic diameter deduced from viscosity measurements for neon, argon, krypton, and xenon, as 1.35, 1.29, 1.22, and 1.23 ...
Figure 3.1 The Structure of the Atom Atoms have protons and neutrons in the center, making the nucleus, while the electrons orbit the nucleus. The modern atomic theory states that atoms of one element are the same, while atoms of different elements are different. What makes atoms of different...
Here the authors discover that the coherent Raman coupling between the cation states leads to extra timedelay between different transition channels by applying the attosecond transient absorption spectroscopy on the investigation of complex dynamics of strong field ionization of Krypton.

Structure that houses a huge database of the knowledge of an entire civilization. Many researchers visit here to learn from the accumulated knowledge. Often left behind by Precursors, though such projects are undertaken by more recent societies as a prestigious project. Expect it to be very quiet...
Chemical element - Geochemical Cycle, Atomic Structure, Reactivity: The preceding discussion has shown that at the time of formation of the Earth the chemical elements already had been considerably fractionated: the universe consists almost entirely of h
