    2019109&ensp·&enspA chemical element is a species of atom having the same number of protons in their atomic nuclei (that is, the same atomic number, or Z). For example, the atomic number of oxygen is 8, so the element oxygen consists of all atoms which have 8 protons.. One hundred eighteen elements have been identified: the first 94 occur naturally on Earth, and the remaining 24 are synthetic elements.
