atomic radius是原子半径。ionic radii是离子半径。这就是区别
Atomic radius is the radius of an atom. It measures the size of an atom. If the element is a metal, then the atomic radius refers to the metallic radius, and if the element is a non-metal, then it refers to the covalent radius. Metallic radius is calculated as half the internuclear...
radius directly for the same reason it is not possible to directly measure an atom’s radius, it is possible to measure the distance between the nuclei of a cation and an adjacent anion in an ionic compound to determine the ionic radius (the radius of a cation or anion) of one or both...
6 determine the numbers of protons, neutrons and electrons present in both atoms and ions given atomic or proton number, mass or nucleon number and charge 7 state and explain qualitatively the variations in atomicradiusand ionic radius across a period and down a group 1.2 Isotopes 1 define the...
Ionic trend is in reference to the trend in ionic radii sizes throughout the periodic table of elements. While looking at a periodic table and moving down a group or column, the period number increases and therefore the atomic radius and ionic radius of those elements increases al...
This article makes a detailed analysis of the definition ofatomic radiusand ionic radius, so that the two terms can be well understood and used in the course of teaching. 本文对原子半径和离子半径的概念进行了较为详细的讨论,以便在教学过程中更好的理解、使用原子半径和离子半径。

1) Atomic radius increases as you go down a group (from top to bottom) on the periodic table.2) The atomic radius increases because the number of energy levels surrounding the nucleusincreases, which makes the atom bigger. 選擇正確的詞語 1 Cation 2 Anion 3 Anion Ionic Radius Key Points: ...
