What is electronegativity trend?

What is electronegativity trend? The electronegativity trend refers to a trend that can be seen across the periodic table. This trend is seen as you move across the periodic table from left to right: the electronegativity increases while it decreases as you move down a group of elements. Which best describes the trends in electronegativity […]

What happens during tempering of steel?

What happens during tempering of steel? Tempering, in metallurgy, process of improving the characteristics of a metal, especially steel, by heating it to a high temperature, though below the melting point, then cooling it, usually in air. The process has the effect of toughening by lessening brittleness and reducing internal stresses. What does tempering do […]

What are the four 4 stages of supply chains?
