Which of the following best describes how the periodic table is organized?

The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.

Which best explains how the modern periodic table is arranged?

In the modern periodic table, the elements are arranged according to their atomic number – not their relative atomic mass . In the periodic table the elements are arranged into: rows, called periods , in order of increasing atomic number. vertical columns, called groups , where the elements have similar properties.

Why is the system that the elements are organized on the periodic table important?

To summarize, the periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one easy-to-use reference. Columns (groups) and rows (periods) indicate elements that share similar characteristics.

Which best explains why the alkali metals are the most reactive group in the periodic table?
