Basic properties Atomic number. The single most important characteristic of an atom is its atomic number (usually denoted by the letter Z), which is defined as the number of units of positive charge (protons) in the nucleus.For example, if an atom has a Z of 6, it is carbon, while a Z of 92 corresponds to uranium.A neutral atom has an equal number of protons and electrons …

1. INTRODUCTION. Some abbreviations used: A = mass number, A r = relative atomic mass, Z = atomic number (NOT z). m/z = relative molecular mass or isotopic mass / electric charge for ions formed in a mass spectrometer. Mass spectrometry gives accurate information on the relative masses of isotopes and their relative abundance (proportions).

Electronic configuration is defined as the distribution of electrons into the orbitals of an atom. Every neutral atom consists of a fixed number of electrons which is equal to the number of protons and is called the atomic number. Apart from electrons and protons, an atom also has neutrons which may or may not be equal to the number of the protons.

Atomic absorption is a special application in which ground-state atoms of metals absorb light at very specific wavelengths corresponding to the energy needed to cause electronic transitions in their electron orbitals. Fig. 7.8 shows the configuration of an atomic absorption spectrophotometer. The atoms are created by heating the sample in an acetylene gas flame or …
