1几道英语化学题!1.how are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on the periodic table?2.how does the number of electrons relate to the arrangement what is the different in the number of electrons in a 3rd period element and the...
The meaning of ATOMIC NUMBER is an experimentally determined number characteristic of a chemical element that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines t
atomic number of an element 指的是：元素X的原子序数是15,核外有15个电子,所以该元素为P元素,即磷元素 而number of electrons in an anion of X问得是：X元素的阴离子核外电子数是多少?因为P的最外层电子是5个电子,所以必须得到3个电子才满足8个电子的饱和结构 所以磷元素的阴离子核外电子数...
