How are protons and neutrons different from and similar to each other? What are some examples of the nuclear fission equation? Why does spontaneous fission occur only in the heaviest nuclei? What is the uranium fission nuclear reaction?
All atoms of an element have the same number of protons and electrons, but the number of neutrons might differ. 同种元素的原子具有相同的质子数和电子数,但中子数可能不同。 For example, there are three types of potassium atoms that occur naturally. All three types contain 19 protons and 19 e...
How are protons and neutrons different from and similar to each other? If the protons and neutrons are not equal, does that mean it is a radioactive isotope? How did the discovery of the neutron lead to nuclear physics? How do you calculate the half-life of a radioactive isotope?

Inside DNA you would find atoms, electrons, protons, neutrons. 在DNA 里面,你可以找到原子、电子、质子、中子。 Deeper still you would find quarks, neutrinos and so on and then, just maybe, continuously deeper into infinity. 再往深处,你会发现夸克,中微子等等,然后,也许,不断深入到无限深处。
How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example, hydrogen atoms have one electron orbiting the nucleus. Helium atoms have two electrons orbiting the nucleus. Aluminum atoms have 13 electrons circling the nucleus. Each atom has a preferred number of ...
The periodic table of elements includes 118 individual types of atoms (that is, elements), all of which have a unique number of protons and electrons and a similar number of neutrons. But just how tiny is this infinitesimally small entity? Is there a way to relate thesize of an atomto ...
In case you're confused: hydrogen ions are simply hydrogen atoms with their electrons removed. Since they have only one proton and one electron to start with, a hydrogen ion is the same thing as a proton. The protons travel through the electrolyte (yellow) towards the positive terminal (...
Astronomers classify all of this stuff as baryonic matter, and they know its most fundamental unit is the atom, which itself is composed of even smaller subatomic particles, such as protons, neutrons and electrons. Unlike baryonic matter, dark matter neither emits nor absorbs light or other forms...
