Question

Give the names of the nonmetals that correspond to the following symbols: As, I, Xe, He, C, Si.

Short answer

The nonmetals that correspond to the given symbols are Arsenic (As), Iodine (I), Xenon (Xe), Helium (He), and Carbon (C).

Step-by-step solution

Identify Nonmetals in the Periodic Table

First, we need to know which of these elements are nonmetals. Nonmetals are generally found on the right side of the periodic table. After looking up the symbols in the periodic table, we find that As, I, Xe, He are nonmetals, while C is also a nonmetal, and Si is a metalloid (semi-metal). Now, we will find the names of the nonmetals based on their symbols.

Determine the Names of the Nonmetals

Using the periodic table, match each chemical symbol with its corresponding element name: - As: Arsenic - I: Iodine - Xe: Xenon - He: Helium - C: Carbon Thus, the names of the nonmetals that correspond to the given symbols are Arsenic, Iodine, Xenon, Helium, and Carbon.

Key concepts

Chemical Symbols

In the world of chemistry, chemical symbols are shorthand representations of the elements. Each element has a unique one or two-letter symbol that is derived from its English or Latin name. For instance, the symbol for Carbon is 'C', while the symbol for Helium is 'He'. When working with chemical symbols, it's important to remember that they are not arbitrary but rather have a history and logic behind them. For example, 'C' stands for Carbon because 'C' is the first letter of Carbon, and 'He' represents Helium, reflecting its name's pronunciation.

Understanding chemical symbols is crucial as they are used universally to denote elements in chemical equations, labelling compounds, and even in the organization of the periodic table. Remembering the symbols and their corresponding elements takes practice, but once mastered, it makes studying chemistry much easier and more efficient.

Element Names

The names of elements are not only a basic language of chemistry but also a means of understanding the history and properties of the elements themselves. Each element's name has a significance; some honor a scientist, some reflect a property of the element, and others indicate its geographical discovery place.

The names of elements, such as Iodine (I), Xenon (Xe), and Arsenic (As), give us a glimpse into their characteristics or history. Iodine, for instance, comes from the Greek 'iodes', meaning violet, which is a hint to its color when in a gaseous state. Similarly, Xenon is derived from the Greek word 'xenos' meaning stranger, reflecting on its rare nature in the Earth's atmosphere. These names are not just identifiers but also enrich the study of chemistry with a deeper context.

Periodic Table Organization

The periodic table is a scientist's roadmap to understanding the elements and their relationships. Its organization is not random; it's a thoughtful arrangement where elements are placed based on increasing atomic number, which is the number of protons in an element's nucleus. Furthermore, elements with similar chemical properties are grouped in columns known as groups or families, and rows called periods reflect elements with increasing atomic mass.

One of the key elements of the periodic table is distinguishing between metals, nonmetals, and metalloids. Nonmetals, which include elements like Helium (He), Carbon (C), and Iodine (I), typically reside on the right side of the table. Metalloids, such as Silicon (Si), have properties in between metals and nonmetals and usually form a staircase line that separates the two. By recognizing the layout of the periodic table, students can predict and understand an element's properties and its reactivity with other elements.
