Final answer:
Chlorine (Cl) is the nonmetal among the given options, as it belongs to Group 17: The Halogens, which is known for its nonmetallic elements. B) Chlorine (Cl) is correct answer.
Step-by-step explanation:
To identify which of the following elements is a nonmetal:
- Sodium (Na)
- Chlorine (Cl)
- Silicon (Si)
- Iron (Fe)
We need to look at the properties of these elements and their position on the periodic table. Sodium (Na) is an alkali metal, Iron (Fe) is a transition metal, and Silicon (Si) is a metalloid.
Among these options, Chlorine (Cl) is the element that is a nonmetal. Specifically, Chlorine is part of Group 17: The Halogens, which includes elements such as fluorine (F), bromine (Br), iodine (I), and astatine (At). These elements are known as nonmetals.
The nonmetal among the given elements is Chlorine (Cl). Chlorine is a member of Group 17 in the periodic table, known as the halogens, which are all nonmetals. The halogens react readily with metals to form compounds like sodium chloride (NaCl) and calcium chloride (CaCl2).
