2019-12-05 · A chemical element is a substance consisting of only one type of atom. In other words, all atoms in an element contain the same number of protons. The identity of a chemical element cannot be changed by any chemical reaction. However, a nuclear reaction can transmute one element into another one. 2020-10-22 · Of the known elements, 11 (hydrogen, nitrogen, oxygen, fluorine, chlorine, and the six noble gases) are gases under ordinary conditions, two (bromine and mercury) are liquids (two more, cesium and gallium, melt at about or just above room temperature), and the rest are solids.
