WebNov 4, 2024 · Here is a table of element valences. Remember that an element's electron cloud will become more stable by filling, emptying, or half-filling the shell. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell. Table of Element Valences Sources WebOut of all the 118 Elements, 98 Elements are found in nature (those with atomic number 1- Hydrogen 'H' to atomic number 98 – Californium 'Cf'; in the periodic table), with the rest being synthesized from the naturally occurring elements, in a laboratory.

For ordinary nuclei, this is equal to the proton number (np) or the number of protons found in the nucleus of every atom of that element. The atomic number can be used to uniquely identify ordinary chemical elements. In an ordinary uncharged atom, the atomic number is also equal to the number of electrons.
