How does the periodic table make it easier for scientists to work with and study elements?

• A. It arranges elements based on their physical state at room temperature.
• B. It organizes elements by increasing atomic number and groups elements with similar chemical properties together.
• C. It lists elements in alphabetical order, making them easier to find.
• D. It groups elements according to their discovery date.

Answer: (B)

Verified step by step guidance

1. Understand that the periodic table is a systematic arrangement of elements that helps scientists predict and understand element properties.
2. Recognize that elements in the periodic table are arranged in order of increasing atomic number, which is the number of protons in an atom's nucleus.
3. Note that elements with similar chemical properties are grouped together in columns called groups or families, which helps in studying trends and reactivity.
4. Realize that this organization allows scientists to identify patterns in element behavior, such as valence electron configurations and periodic trends like electronegativity and atomic radius.
5. Conclude that the periodic table's structure makes it easier to work with elements by providing a clear framework to compare and predict chemical properties, rather than organizing by physical state, alphabetical order, or discovery date.
