Which of the following elements is the most chemically reactive? \\ a. hydrogen b. helium c. neon d. argon e. They all have the same chemical reactivity Which elements in the periodic table are referred to alkali metals? Describe the trend in ionization energy from top to bottom down a ...
Extraction of metals Most metals are only found as compounds because the metal has reacted with other elements in the past. Because of this, the metal has to be extracted from the ore (rock) where the metal compound is found. Want to learn more aboutReactivity Series?
Metals are elements found on the left side of the periodic table. Their ability to hold onto their valence electrons is related to ionization energy, which is the amount of energy required to remove an electron from an atom. The lower the ionization energy, the more easily a ...
Metals above carbon in the reactivity series are extracted by electrolysis, while those below carbon are extracted by reduction with carbon.Chinese: 活泼性顺序决定金属提取的方法,指示金属还原的难易程度。活泼性顺序中位于碳以上的金属通过电解法提取,而位于碳以下的金属通过碳还原法提取。Q3: What is a ...
(d). State three reasons (of which at least one must be chemical) for believing that sulphur is a non-metal. (e). Which non-metal has been placed in the reactivity series of metals. View Solution You are given a hammer, a battery, a bulb, wires and a switch. (a) How could ...
Here's the scientific definition of what makes a metal as well as how metals are defined according to their position on the Periodic Table.
\(\begin{array}{l}reactivity\ of\ non-metals = electron\ affinity\end{array} \) \(\begin{array}{l}oxidising\ power\ of\ element = electron\ affinity\end{array} \) 1. atomic size: if the atomic size is small, then there will be greater electron gain enthalpy because the effective ...
