The periodic table of elements provides information on each element, including:
1. Element symbol: A one or two-letter symbol representing the element. For example, "H" for Hydrogen and "O" for Oxygen.
2. Atomic number: The number of protons found in an atom's nucleus, which determines the element's identity. Elements are arranged in the periodic table based on their atomic numbers.
3. Element name: The name given to the element, corresponding to its symbol. For example, "Hydrogen" and "Oxygen."
4. Atomic mass: The average mass of an atom of that element, which is usually expressed in atomic mass units (amu).
5. Atomic structure: This reveals the number and arrangement of subatomic particles in an atom, including the number of protons, neutrons, and electrons.
6. Electron configuration: The electron arrangement in different energy levels or shells around the atom's nucleus.
7. Group: Elements in the same vertical column, or group, possess similar chemical properties.
8. Period: Elements in the same horizontal row belong to the same period.
9. Electron affinity: The energy change that occurs when an electron is added to a neutral atom.
10. Ionization energy: The energy required to remove an electron from an atom, resulting in the formation of a positive ion.
11. Metallicity: Indicates whether an element is a metal, non-metal, or metalloid.
12. Melting point: The temperature at which a solid element transforms into a liquid state.
13. Boiling point: The temperature at which a liquid element transforms into a gaseous state.
14. Electronegativity: The ability of an atom to attract electrons towards itself in a chemical bond.
15. Oxidation states: Shows the possible charges an element can have when it forms compounds.
16. Natural occurrence: Information about the element's occurrence in nature, such as whether it is commonly found or rare.
17. Atomic radius: The size of the atom, typically measured as the distance from the nucleus to the outermost electron shell.
18. Density: The mass of the element per unit volume.
19. Discovery and naming: The date and person credited with the discovery of the element and the origin of its name.
These are some of the key pieces of information typically available on the periodic table of elements.
