Whose reactivity is highest among the following metals ? 1 point coppe...
Answer:
Introduction:
In chemistry, reactivity refers to how easily an element or compound undergoes a chemical reaction. Metals are one of the most reactive groups of elements, and their reactivity is determined by the ease with which they lose electrons. In this question, we are asked to determine which among copper, potassium, iron, and zinc has the highest reactivity.
Explanation:
To determine the reactivity of these metals, we need to look at their position in the periodic table. The reactivity of metals generally increases as we move down and to the left of the periodic table. This is because, as we move down, the number of electron shells increases, and the distance between the nucleus and the outermost electrons also increases, making it easier for the outermost electrons to be lost. As we move to the left, the number of valence electrons increases, making it easier for the electrons to be lost.
Comparison:
- Copper (Cu): Copper has an atomic number of 29, and it is located in Group 11 of the periodic table. Copper has a low reactivity because it has a full valence shell and is not easily oxidized.
- Potassium (K): Potassium has an atomic number of 19, and it is located in Group 1 of the periodic table. Potassium has a high reactivity because it has only one valence electron, making it easy to lose that electron and form a cation.
- Iron (Fe): Iron has an atomic number of 26, and it is located in Group 8 of the periodic table. Iron has a moderate reactivity because it has two valence electrons, but it is not as easily oxidized as potassium.
- Zinc (Zn): Zinc has an atomic number of 30, and it is located in Group 12 of the periodic table. Zinc has a moderate reactivity because it has two valence electrons, but it is not as easily oxidized as potassium.
Conclusion:
Based on the above discussion, we can conclude that potassium has the highest reactivity among the given metals because it has only one valence electron, making it easy to lose that electron and form a cation. Copper has the lowest reactivity because it has a full valence shell and is not easily oxidized.
