Write the chemical symbol for an element belonging to each of the element families in the table below.
| element family | example element |
| --- | --- |
| halogen | $\square$ |
| chalcogen | $\square$
Answer (2)
Identify a halogen: Fluorine (F) is a halogen.
Identify a chalcogen: Oxygen (O) is a chalcogen.
The chemical symbol for a halogen is F.
The chemical symbol for a chalcogen is O. F , O
Explanation
Understanding the Problem The problem asks for the chemical symbol of an element from the halogen family and an element from the chalcogen family. Halogens are group 17 elements, and Chalcogens are group 16 elements.
Identifying a Halogen Let's identify a halogen. Fluorine (F) is a halogen.
Identifying a Chalcogen Now, let's identify a chalcogen. Oxygen (O) is a chalcogen.
Final Answer Therefore, the chemical symbol for a halogen is F, and the chemical symbol for a chalcogen is O.
Examples
Understanding the properties and positions of elements in the periodic table is crucial in chemistry. For instance, knowing that halogens are highly reactive nonmetals helps in predicting their behavior in chemical reactions, such as the formation of salts. Similarly, recognizing chalcogens like oxygen and sulfur is essential in understanding the composition of many minerals and their roles in biological processes. This knowledge is fundamental in fields ranging from materials science to environmental chemistry.
The chemical symbol for a halogen is F (Fluorine), and the chemical symbol for a chalcogen is O (Oxygen).
