(Electrons within a shell have very similar energies and are at similar distances from the nucleus.) In the chemical elements of atomic number 17 to 19, for example, the chloride ion (Cl−), the argon atom (Ar), and the potassium ion (K+) have 18 electrons in closed-shell ...
The symbol Z is given to that atomic number, which is also the number of electrons in the atom and determines its chemical properties. Computer Exercise 2.A describes the program ELEMENTS, which helps find atomic numbers, symbols, and names of elements in the periodic table. Generally, the ...

There are about ninety elements found on Earth. Each one has a different number of protons, electrons and neutrons. The total number of these subatomic particles held by the respective elements are responsible for their unique properties (including radioactivity). ...
What we have been attempting to do for the last 40 years is to develop a dynamic, integrated, computerized system covering all chemical-chemical interactions and chemical-biological interactions. We enter any information into this system of chem.-bioinformatics that can be described in mathematical ...
