The tiny atoms that make up our world are made up of even tinier protons, neutrons and electrons. Though the number of protons determines an atom's identity, it's the electrons -- specifically, their exact location outside the nucleus -- that particularl
aToday’s model of the atom has a concentrated nucleus containing the protons and neutrons surrounded by a cloud representing where the electrons are likely present. 原子的今天模型有一个被集中的中坚力量包含云彩和中子围拢的氢核代表电子是可能的存在的地方。[translate] ...
