What does the atomic number of an element tell you about the element? Structure of Atom: An atom comprises of a very tiny and dense particle called nucleus, which carries the protons and neutrons in it, while electrons are found in the orbit of suitable quantum number surrounding ...
The atomic number of an element X is 15.The number of electrons in an anion of X is?答案是D,但是eleltrons不是等同atomic number吗?A 10B 12C 15D 18 答案 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 anio...
Elements are characterised by mass of their atoms so all the atoms of an element have identical weight. Different elements have atoms of different atomic weight. Atoms of different elements can combine together to form chemical compounds. When elements undergo chemical reactions, their atoms combine ...
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是:15+3=18所以...

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)
