Related to this QuestionHow many protons, neutrons, and electrons are in 40K? State its atomic number and mass number. An element has an atomic number of 114 and an atomic mass of 285. How many protons, neutrons, and electrons does a neutral atom of ...
In a bomb that is working properly, more than one neutron ejected from each fission causes another fission to occur. It helps to think of a big circle of marbles as the protons and neutrons of an atom. If you shoot one marble — a single neutron — into the middle of the big circle...

Atomic number:The number of protons in an atom's nucleus is referred to as the atomic number of that element. The number of protons defines what element it is and determines its chemical behavior. For example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalw...
They can, however, knock an electron away from an atom altogether. Some of the energy from the X-ray photon works to separate the electron from the atom, and the rest sends the electron flying through space. A larger atom is more likely to absorb an X-ray photon in this way, because...
How does an atom try to fill its valence shell? How do you find the valency of an element? How can one find the valency of an element? The atomic mass of the element is determined by the combined masses of neutrons and protons. True or false? Explain. How do you cou...
When an unstable atom disintegrates, it produces particulate radiation, including alpha and beta particles. For example, when radioactive elements like uranium, radium and polonium decay, they release radioactive alpha particles. These particles, made up of protons and neutrons, are large and can ...
