The number of protons present in an atom leads to the termatomic number. An atomic number 1 points out that the atom is hydrogen. Similarly, an atomic number 2 reveals helium atom. The total number of neutrons and protons, when added together, gives us the relative atomic mass. For exampl...
Atoms are made up of a nucleus, protons and electrons. ... Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled,
Therefore, an identical spin and parity was confirmed for any pair. In addition, the EB/A difference of mirror nuclei pair is nearly a constant of 0.184n MeV. Many other facts can also be easily understood from this model, such as the neutron halo, the unusual stability sequence of 9Be,...

A new test that takes data from several realms of physics could explain what really happened in the first sliver of a second after the Big Bang. Most cosmologists believe the universe burst from an extremely dense, hot state around 13.7 billion years ago
Deployment: Due to its size, the MOAB is delivered by a C-130 military transport plane, guided by a GPS system and deployed via parachute. "Such enormous munitions may make a big blast, but they are not guaranteed to wipe out enemy fighters burrowing deep underground," Max Boot, a senior...
mass and atomic number and found differences. If the nucleus only had “+” and “-” inside these would be the same but they are not, they were double. There must be something else inside. Even though it is the same mass as a proton it is electrically neutral, hence the name ...

In the past, governments and big-money interests have glossed over alerting the public to these technologies because it was much more profitable to encourage dependence on the current system. But now that the current system is in trouble, with ever more bailouts, skyrocketing fuel costs, and fa...
The big difference between a maglev train and a conventional train is that maglev trains do not have an engine — at least not the kind of engine used to pull typical train cars along steel tracks. The engine for maglev trains is rather inconspicuous. Instead of using fossil fuels, the mag...
