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...

How does the element definition relate to the atomic number? Solution Step 1 Solution:− Theatomicnumberofanelement, represented by the symbol(Z), is fundamental to the definition and identity of the element. View the full answer
Atoms of an element are all the same in terms of shape and size and atoms of different elements differ in size and shape. 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 ...
hg hg . 80 atomic number hg element symbol mercury element name 200.59 average atomic mass the atomic weight is a measurement of the total number of particles in an atom's nucleus including both protons and neutrons. so the first step is to locate the atomic mass on the periodic table, ...
The atomic mass of the element is determined by the combined masses of neutrons and protons. True or false? Explain.Answer and Explanation: The atomic mass or atomic weight of an element (or put it in simple term, mass of an atom) is found by...
