What is the name of the chart that organizes elements by increasing atomic number?

• A. Periodic Chart
• B. Atomic Ledger
• C. Periodic Table
• D. Element Grid

Answer: (C)

Organizing elements by increasing atomic number reveals how their identities and properties repeat in a predictable way. The chart that does this and also groups elements with similar chemistry is the periodic table. By arranging elements in order of the number of protons, the periodic table shows trends in reactivity, size, and electron configuration as you move across rows (periods) and down columns (groups). This setup makes it easy to predict how elements will behave and how they bond with others. The standard name for this chart is the periodic table; other proposed terms aren’t the standard usage in science.
