Scientists discovered that atoms of some substances are radioactive. This means that they are unstable and can be split. The chain of splitting atoms releases great destructive energy and it was this discovery which led scientists to develop the idea of an atomic bomb. The American government sec...
Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.

Why are large atoms more polarizable?Polarizability:Polarizability is described as an atomic property that refers to its tendency to acquire a dipole moment in proportion to the applied field. It is affected by various factors such as atomic radii, electron density, and molecular orientation in ...
NEUTRONS ARE DECAYING EXCITED HYDROGEN ATOMS H ---> p + e + Q 来自 ResearchGate 喜欢 0 阅读量: 8 作者: J Marinsek 摘要: Hydrogen atoms are destabilized during decomposition of the atom Unstable neutrons are not components of the atoms All atoms are made up of hydrogen The discoverer...
How many atoms are there in something? If atoms are so tiny, there must be zillions and zillions of them in all the things around us... but how many are there, exactly? Chemists have a handy way of talking amount these vast numbers of atoms—by using the rather unusual word mole. A...

Free radicals areunstable atomsthat can damage the cells in the body. What makes them so unsteady? They’re oxygen-containing molecules that have an unpaired electron. That single electron allows them to interactfreelywith other molecules, which isn’t always a good thing. ...
The r-process begins when the seed nuclei of iron are bombarded with these free neutrons, soaking them up. Stableatomsof iron, such as the isotope iron-56, have 26 protons and 30 neutrons. The excess of neutrons granted to iron by neutron capture makes the iron atoms unstable and radioact...
