Atomic number

The position identification of an element in the periodic table and the determining factor of its chemical properties

Atomic number refers to the number of protons contained in the nucleus of an element atom, and this value has the following core characteristics:

Element uniqueness: Each element corresponds to a specific atomic number (e.g., hydrogen=1, carbon=6, oxygen=8)

Chemical behavior basis: Directly determines the electronic configuration and chemical properties of elements

Periodic law foundation: The periodic table is arranged in increasing atomic number, forming periodic patterns of element properties

Water treatment application relevance:

Identification of radioactive elements (such as uranium-92, radon-86)

Ion exchange resin selection criteria (charge matching principle)

Detection and localization of heavy metal pollutants (cadmium 48, lead 82, etc.)
