42. Which of the following is true about reactivity?1 pointthe most reactive metals are the most stablethe most reactive metals have high atomic radiusthe most reactive metals have high electronegativitythe most reactive metals have high ionization energythe most reactive metals gain electrons the most easily
Solution
The statement that is true about reactivity is: "the most reactive metals gain electrons the most easily".
Here's why:
-
The most reactive metals are not the most stable. In fact, it's the opposite. The most reactive metals are the least stable because they readily participate in chemical reactions.
-
The most reactive metals do not necessarily have a high atomic radius. The reactivity of metals is not directly related to their atomic radius.
-
The most reactive metals do not have high electronegativity. Electronegativity is the measure of the ability of an atom to attract electrons. Metals, especially the most reactive ones, tend to lose electrons rather than gain them, so they have low electronegativity.
-
The most reactive metals do not have high ionization energy. Ionization energy is the energy required to remove an electron from an atom. The most reactive metals have low ionization energies because they can easily lose electrons to form positive ions.
-
The most reactive metals gain electrons the most easily. This is not true for metals. Metals are elements that lose electrons easily. However, for non-metals, the most reactive ones gain electrons the most easily.
