1 An atom of an element has an atomic number of 6 and a mass number of 12.(a)Using this information, complete the table to show the numbers of protons,neutrons and electrons in one atom of this element.(2)number of protons number of neutrons number of electrons(b)The Periodic Table ...
解析 首先句子后面是作定语的,由主句可以知道,修饰的是主语element.因为atoms是原子的意思,对于元素来说,逻辑关系自然是“元素里的原子”,所以element和atoms具有从属关系,用whose(注意啦!在定语从句表示从属关系的时候,关系词whose不仅仅适用于人,也可以适用于物)...

The notation we use to identify a particular nuclear composition of an atomic element E with atomic number A=Z+N is ZAE, ZEA, or just AE. Atomic species with identical chemical properties (same Z) but distinct masses (different A) are called isotopes. Nuclides with the same A are...
Cs Cesium is a silvery-gold, soft, light, and tough metallic element with atomic number 55, and its melting and boiling points are 28.44 °C and 671.4 °C, respectively. Zhang et al. [110] fabricated a novel whisker-supported IIP through surface ion imprinting and polysaccharide-incorporated...
