A. A chart that lists all the molecules that exist in the universe
B. A chart that shows all the elements scientists have discovered
C. A chart that shows all the compounds found in the world
D. A chart that shows what time period elements were discovered in

Answer 1

The periodic table is a chart that shows all the elements scientists have discovered and organizes them based on their chemical properties. Option B is correct..

Step-by-step explanation:

The periodic table is a chart that shows all the elements scientists have discovered. It organizes the elements based on their chemical properties and provides additional data such as atomic mass and symbol. The elements are listed in order of atomic number, with hydrogen and helium at the top.

The periodic table is essentially a chart that displays all the elements scientists have discovered, organized by their chemical properties. Each element's listing includes its chemical symbol, atomic number, and often its atomic mass. Elements are arranged in order of increasing atomic number in rows, and grouped by similar chemical properties in columns. There are currently 118 acknowledged elements, ranging from hydrogen, with an atomic number of 1, to oganesson, with an atomic number of 118.
