One effect of the spirited give-and-take of these discussions was to focus attention on practical applications and the necessity of being armed with the facts: knowledge of the destructive force of even the tiniest `` tactical '' atomic weapon would have a bearing on judgments as to the advisability of its use -- to defend Berlin, for example ; ;
The latter is not to be confused with TA ( NPL ), which denotes an independent atomic time scale, not synchronised to TAI or to anything else.
Early atomic time scales consisted of quartz clocks with frequencies calibrated by a single atomic clock ; the atomic clocks were not operated continuously.
The atomic number, Z, should not be confused with the mass number, A, which is the number of nucleons, the total number of protons and neutrons in the nucleus of an atom.
Only after 1915, with the suggestion and evidence that this Z number was also the nuclear charge and a physical characteristic of atoms, did the word and its English equivalent atomic number come into common use.
This led to the conclusion ( Moseley's law ) that the atomic number does closely correspond ( with an offset of one unit for K-lines, in Moseley's work ) to the calculated electric charge of the nucleus, i. e. the proton number Z.
Hence it is the atomic number alone that determines the chemical properties of an element ; and it is for this reason that an element can be defined as consisting of any mixture of atoms with a given atomic number.
As of 2010, elements with atomic numbers 1 to 118 have been observed.
Synthesis of new elements is accomplished by bombarding target atoms of heavy elements with ions, such that the sum of the atomic numbers of the target and ion elements equals the atomic number of the element being created.
In general, the half-life becomes shorter as atomic number increases, though an " island of stability " may exist for undiscovered isotopes with certain numbers of protons and neutrons.

Actinium ( ) is a radioactive chemical element with symbol Ac and atomic number 89, which was discovered in 1899.
Giesel, on the other hand, can rightfully be credited with the first preparation of radiochemically pure actinium and with the identification of its atomic number 89.
Astatine ( or ) is a radioactive chemical element with the chemical symbol At and atomic number 85.
The melting and boiling points of astatine are also expected to follow the trend seen in the halogen series, increasing with atomic number.
The atomic nucleus contains a mix of positively charged protons and electrically neutral neutrons ( except in the case of hydrogen-1, which is the only stable nuclide with no neutrons ).
Over 99. 94 % of an atom's mass is concentrated in the nucleus ,< ref group = note > In the case of hydrogen-1, with a single electron and nucleon, the proton is, or 99. 95 % of the total atomic mass.
