Which table groups elements by similar chemical properties and lists their atomic numbers and symbols?

• A. Gravitational chart
• B. Weather map
• C. Nutritional table
• D. Periodic table

Answer: (D)

Grouping elements by similar chemical properties and listing their atomic numbers and symbols describes the periodic table. It organizes elements in order of increasing atomic number, which is the number of protons in an atom, and gives each element its own symbol. Elements that lie in the same vertical column tend to behave similarly because they have the same number of valence electrons, guiding their reactivity and the kinds of compounds they form. As you move across a row, properties change in a predictable way, showing patterns you can use to infer how different elements will act. The other options aren’t about chemistry elements and their identities or properties—gravitational charts relate to gravity, weather maps show atmospheric conditions, and nutritional tables list foods or nutrients. So this table is the one that groups elements by chemical properties and lists atomic numbers and symbols.
