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? 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?
A beta particle is a high speed electron from the nucleus. This is not to be confused with electrons in the electron cloud. If the nucleus consists of only protons and neutrons, how is it possible for How are radioactive isotopes detected?

Atoms and ions consist of electrons that occupy orbitals somewhere around the nucleus of the atom. Orbitals are spaces around the nucleus that an electron has the greatest likelihood of occupying. Different orbitals have different energy levels and electrons will tend to occupy orbitals with the lowe...
甚至原子里的电子也会被剥离 Even the electrons around your atoms will be ripped apart. 末日将临 The end is coming, 可能比你想像的还要快 and it could be sooner than you think. 了解宇宙如何运行 第三季 宇宙的终结 宇宙就是一切 The universe is everything 一切空间 一切时间 一切物质 all space,...
When that happens, the original element drops down to a full shell and the second electron completes its upper shell; both elements are now stable. However, because the number of electrons and protons in each element are no longer equal, the element that received the electron now has a net...
the presence of equal numbers of protons and electrons leaves an atom neutrally charged. section1 current and voltage we consider the flow of electric charges. a unique feature of electric charge or electricity is the 5、 fact that it is mobile; that is, it can be transferred from one ...
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 ...
