Atomic number: 16
The atomic number corresponds to the number of protons in the nucleus of an atom of that element. It also corresponds to the number of electrons in the neutral atom.
Atomic mass: 32.065
"An atomic weight (relative atomic mass) of an element from a specified source is the ratio of the average mass per atom of the element to 1/12 of the mass of 12C" in its nuclear and electronic ground state. (Refs. 1 and 2)
The name by which elements are known (ref. 1) is dependent upon language and indeed upon language variants. See below for differences in names used for English and American variants of English. The origins of the names of the elements are given in refs. 2 and 3. Controversy (see below) regarding names of a few heavy elements is now resolved (ref. 4). Names for elements 110-112 have yet to be proposed. Temporary IUPAC systematic names for elements with atomic numbers greater than 100 are given in ref. 5.
