What is the most reactive family on the periodic table?Group of answer choicesnoble gaseshalogensalkali metalsalkaline earth metals

To determine the most reactive family on the periodic table, we need to consider the properties of the given options: noble gases, halogens, alkali metals, and alkaline earth metals.

1. Noble gases: Noble gases are known for their low reactivity. They have a full outer electron shell, making them stable and less likely to form chemical bonds with other elements. Therefore, noble gases are not the most reactive family.

2. Halogens: Halogens are highly reactive nonmetals. They have seven valence electrons and tend to gain one electron to achieve a stable electron configuration. Halogens readily form compounds with other elements, especially alkali metals. Due to their high reactivity, halogens are a strong contender for the most reactive family.

3. Alkali metals: Alkali metals are highly reactive metals. They have one valence electron and tend to lose it to achieve a stable electron configuration. Alkali metals react vigorously with water and oxygen, and they are known for their explosive reactions. Therefore, alkali metals are also strong contenders for the most reactive family.

4. Alkaline earth metals: Alkaline earth metals are also reactive metals, but they are less reactive than alkali metals. They have two valence electrons and tend to lose them to achieve a stable electron configuration. While alkaline earth metals can react with certain substances, their reactivity is lower compared to alkali metals and halogens.

Based on the information provided, the most reactive family on the periodic table is likely the halogens. They exhibit high reactivity due to their tendency to gain one electron and form compounds with other elements.
