The periodic table primarily contains the following:
- The elements that have been discovered so far: The periodic table lists all known chemical elements, organized by their atomic number, electron configuration, and recurring chemical properties.
The other options mentioned—products that make up different types of substances, the number of electrons found in the nucleus, and the compounds used in daily life—are not directly found on the periodic table:
-
The products that make up different types of substances: While the elements do combine to form various substances, specific products or mixtures are not depicted on the periodic table.
-
The number of electrons found in the nucleus: This statement is inaccurate; the number of electrons in an atom is equal to the atomic number when the atom is neutral, and electrons are not located in the nucleus (they occupy orbitals around the nucleus).
-
The compounds that are used in your daily life: The periodic table does not list compounds. It only lists the elements that can combine to form those compounds.
In summary, the primary information found on the periodic table is the elements themselves.
