Atomic numbers were first worked out in 1913 by Henry Moseley, a young member of Rutherford's research group in Manchester. You can think of the atomic number as a kind of serial number of an element, commencing at 1 for hydrogen and increasing by one for each successive element.
Atomic absorption analysis involves measuring the absorption of light by vaporized ground state atoms and relating the absorption to concentration. The incident light beam is attenuated by atomic vapor absorption according to Beer's law. The process of atomic absorption spectroscopy (AAS) involves two steps: 1. Atomization of the sample . 2.
Then calculate the electronic configuration using the atomic number 2+8+7=17 therefore the electronic configuration will be 2, 8, 7. 3. Here we find that the no of valence electrons of element is 7 as the valence shell has 7 electrons.

 Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the neutron number and the atomic number is known as the neutron excess : D = N – Z = A – 2Z. Neutron number is rarely written explicitly in nuclide symbol notation, but appears as a subscript to the right of the element symbol.
