A. Si, As, and Te
B. Mg, Sr, and Ba
C. N2, O2, and F2
D. Ca, Cs, and Cu
Please explain your answer.
Answer (3)
Chemical properties are characteristics of a substance that describe how it interacts or reacts with other substances, leading to changes in its composition or structure. The correct answer is C. N₂, O₂, and F₂.
These properties help define the chemical behavior of a substance and are determined by its chemical composition and atomic/molecular structure.
N₂ (nitrogen gas), O₂ (oxygen gas), and **F₂ (fluorine gas) **belong to the same group/family on the periodic table, known as group 16 or the oxygen family . Elements within the same group tend to have similar chemical properties because they have the same number of valence electrons, which are the electrons involved in chemical bonding.
In the case of N₂, O₂, and F₂, they all have** six valence electrons**. This similarity in electron configuration leads to comparable chemical behavior, including their tendency to form covalent bonds, their reactivity, and their ability to gain electrons to achieve a stable octet.
Therefore, the correct answer is C. N₂, O₂, and F₂ .
