Since it is easier to remove an electron from a large atom than from a small one, metallic character increases as we descend the groups in the periodic table. 由于半径较大的原子比半径较小的原子更容易失去电子，因此周期表中同一族从上到下金属性依次增强。Thus in Group lV, carbon i...
Non-metallic character, on the other hand, refers to the tendency of an element to gain electrons and form negative ions, a trait common among non-metals. This character is associated with properties such as brittleness, lack of luster, and poor conductivity of heat and electricity. Non-metall...
Metallic and Non-Metallic Character We know that elements can either be metals or non-metals. But did you ever wonder if one metal is more metallic than the other? Yes. Steel, which is an alloy ofiron, is more metallic than iron. Why is that? This is because of the metallic and non...
fluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alternatives such as alcohol- or galinstan-filled glass thermometers and thermistor- or infrared-based ele...

Lesson 2 Metallic Character 金属性Metals are electropositive and have a tendency to loss electrons, if supplied with energy: MM+e. 金属具有电正性,即在具有足够能量的情况下,趋向于失去电子:MM+e。The stronger this tendency, the more electropositive and more metallic an element is. 失电子的趋势越...
This chapter discusses the metallic face of boron. The properties of the element are reviewed and an idea of the relationship of boron to the other elements in terms of metallic character is presented. The chapter presents structural evidence delineating the similarities and differences of borane ...
An Element. Cupr > generalThere is another symptom which Farrington thought very valuable, viz. "Mental and bodily exhaustion from overexertion of mind, or loss of sleep." This is similar to Cocculus and. Nux vomica. The other symptoms must decide between them. I have always used the ...
Their importance lies in their distinctive character and the situation in which each one finds itself. The characteristics, attributes or traits that make up and reflect what a phase is in an alloy (polis/city) link it with the other phases. For example, a “conventional” solid solution is...
reserves of tantalum, and the Democratic Republic of the Congo has most of these reserves. African reserves of niobium (columbium; a steel-gray metallic elementresemblingtantalum in its chemical properties that is used in alloys) are relatively small. Nigeria, however, is an important world ...
