The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties.

This ordering shows periodic trends, such as elements with similar behaviour in the same column.

It also shows four rectangular blocks with some approximately similar chemical properties.

In general, within one row (period) the elements are metals on the left, and non-metals on the right.

Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter.

Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances.

A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process.

Tool use by humans dates back millions of years, and other animals are also known to employ simple tools.

A fact is something that has occurred or is correct.

The usual test for a statement of fact is verifiability—that is, whether it can be demonstrated to correspond to experience.

Standard reference works are often used to check facts.

Scientific facts are verified by repeatable careful observation or measurement (by experiments or other means).

Data (or) is a set of values of qualitative or quantitative variables.

An example of qualitative data would be an anthropologist's handwritten notes about his or her interviews with people of an Indigenous tribe.

Pieces of data are individual pieces of information.

While the concept of data is commonly associated with scientific research, data is collected by a huge range of organizations and institutions, including businesses (e.g., sales data, revenue, profits, stock price), governments (e.g., crime rates, unemployment rates, literacy rates) and non-governmental organizations (e.g., censuses of the number of homeless people by non-profit organizations).
