Electrons in atoms occupy energy levels, also called electron shells, outside the The electronic structure of an atom can be predicted from its atomic number.

(Atomic Physics) the concept of an atom as a central positively charged nucleus consisting of protons and neutrons surrounded by a number of electrons. The number of electrons is equal to the number of protons: the whole entity is thus electrically neutral. Want to thank TFD for its existence? According to this model, the path of an electron around the nucleus is an ellipse with the nucleus at one of its foci. The angular momentum of an electron in a closed elliptical path is also quantised.

• The relative atomic mass of an element is the average mass of the isotopes of that element, as they occur naturally, taking abundances into account and expressed on a scale relative to 1/ 12 of the mass of an atom of 12C. Calculations: Relative Atomic Masses Silicon has the isotopic composition: silicon-28 = 92.2% silicon-29 = 4.7%
