Examine Figure 2.3, The periodic table. (g) What is the symbol for the element located in period 3, group 4A?

Verified step by step guidance

1. Identify the location of period 3 on the periodic table. Periods are the horizontal rows, so locate the third row from the top.
2. Find group 4A on the periodic table. Groups are the vertical columns, and group 4A is typically labeled as such, or as group 14 in newer notations.
3. Locate the intersection of period 3 and group 4A. The element that resides at this intersection is the one you are looking for.
4. Identify the symbol of the element found at the intersection of period 3 and group 4A.
5. Verify the symbol corresponds to the correct element by checking its atomic number and comparing it with a reliable source or a detailed periodic table.

Key Concepts

Periodic Table

The periodic table is a systematic arrangement of elements based on their atomic number, electron configuration, and recurring chemical properties. Elements are organized into rows called periods and columns known as groups or families. Understanding the layout of the periodic table is essential for identifying elements and predicting their behavior in chemical reactions.

Periods and Groups

In the periodic table, periods are horizontal rows that indicate the number of electron shells an element has, while groups are vertical columns that group elements with similar chemical properties. For example, elements in group 4A (or group 14) share characteristics such as their ability to form four bonds. Recognizing the significance of periods and groups helps in locating elements and understanding their reactivity.

Element Symbols

Each chemical element is represented by a unique one- or two-letter symbol, which is derived from its name, often in Latin or Greek. For instance, the symbol for carbon is 'C', while silicon, located in group 4A, is represented by 'Si'. Familiarity with these symbols is crucial for interpreting chemical formulas and equations, as well as for answering questions related to specific elements.
