Answer :
Final answer:
Chlorine is a nonmetal (2), characterized by its gaseous state at room temperature and its tendency to gain electrons in chemical reactions.
Explanation:
Chlorine is a nonmetal. It is located in group 17 of the periodic table, which is also known as the halogen group. Elements in this group are characterized by their tendency to gain electrons and form negative ions, known as anions, in chemical reactions. Chlorine is therefore classified as a nonmetal due to its properties which include being a gas at room temperature, having a high electronegativity, and lacking the metallic characteristics of luster, malleability, and conductivity.
Chlorine is a nonmetal. the correct option is 2) nonmetal
Chlorine is classified as a nonmetal. It is located in Group 17 of the periodic table, which is known as the halogen group. Elements in this group are typically nonmetals. Chlorine specifically is a greenish-yellow gas at room temperature and is highly reactive, particularly with metals and hydrogen.
Examples of Chlorine's Characteristics:
Physical State: Gas at room temperature
Reactivity: Highly reactive, particularly with metals to form salts (e.g., sodium chloride)
Group Number: 17 (Halogens), which primarily consists of nonmetals
Understanding the classification of elements based on their properties and location in the periodic table is fundamental in chemistry.
Thus, the correct option is 2) nonmetal
