What makes atoms spread out around a central atom? Which force keeps electrons orbiting the nucleus: the strong or weak force? What does the electrostatic force do inside the nucleus? What makes up the nucleus of an atom? Which two fundamental forces have been resolved into one?
The very large difference in electronegativity between the H atom (2.1) and the atom to which it is bonded (4.0 for an F atom, 3.5 for an O atom, or 3.0 for a N atom), combined with the very small size of a H atom and the relatively small sizes of F, O, or N atoms, leads...
While the stable nuclei well inside the valley of stability of the nuclear chart do not show any halo structure in their ground states, they may form an s-wave halo of a core nucleus and a neutron if they are excited in the vicinity of the one-neutron sepa- ration threshold, around ...
where a neutron can turn into a proton plus an electron and anti-neutrino, which is one type of radioactive decay. Weak interactions explain how particles can change by changing the quarks inside them.
What fundamental forces are at work inside an atom? What makes an atom radioactive? What is nuclear energy? Which is a characteristic of nuclear fusion but not nuclear fission? What properties of radioactive isotopes make them useful? What is the role of electrical forces in nuclear fission?
These forces are in an ascending series, but seem to leave no room for the individual; man or atom, he only shares them; he sails the way these irresistible winds blow. But behind all these are finer elements, the sources of them, and much more rapid and strong; a new style and seri...
Under this assumption, if a steroid hormone molecule such as 17β-estradiol (E2) is introduced inside the VaCNT membrane pore, the hydrodynamic drag force \({F}_{{{\rm{H}}}\) acting on the hormone molecule will increase proportionally with the flow velocity via Eq. (3), even when ...
Is there any electric field inside the cell? Is there any electric field outside the cell?Glossarydipole: a molecule’s lack of symmetrical charge distribution, causing one side to be more positive and another to be more negativepolar molecule: a molecule with an asymmetrical distribution of ...
These constraints are highly sensitive to the choice of a density profile inside the clump and are obtained for the most "conservative" BGZ [21] model. It should be also noted that the suppression of the subdominant fraction of DM particles in clumps of mass < min has not been taken into...
What fundamental forces are at work inside an atom? Is there any relationship between intermolecular forces between particles and internal energy of particles at different phases? If there is, how are they related? Why are magnets non-contact forces? How does the weak force effect atoms? What ...
