Determining the charge of an atom is easy in most cases but not all. Atoms are held together by the electromagnetic forces between the protons in the nucleus and the electrons surrounding it, and this means that most of the time there isn't actually much to work out. But when elements lo...
Because these extremely small masses expressed in scientific notation are difficult to work with, chemists have developed a method of measuring the mass of an atom relative to the mass of a specific atomic standard. 由于非常小的质量在科学中难以表达,化学家发展了测量原子相对质量的方法,我们需要一个...

Aluminum alloys play an important role in circular metallurgy due to their good recyclability and 95% energy gain when made from scrap. Their low density and high strength translate linearly to lower greenhouse gas emissions in transportation, and their excellent corrosion resistance enhances product lo...
It is not uncommon for a cosmic ray to collide with an atom in the upper atmosphere, creating a secondary cosmic ray in the form of an energetic neutron, and for these energetic neutrons to collide with nitrogen atoms. When the neutron collides, a nitrogen-14 (seven protons, seven neutrons...
