The proposed formalism is tested on the example of the capture cross section with ionization of the collision of a helium atom with protons. The results obtained are shown to be in good agreement with experimental data.doi:10.1007/BF00898542A. P. KovachUzhgorod State UniversityV. Yu. LazurUzhgorod State UniversityYu. Yu. MashikaUzhgor...
Silicon has 14 protons and 14 electrons; two electrons are required to fill the first electron shell and eight to fill the second shell. Thus, only four remain for the third shell, which would ideally prefer eight. Under the appropriate conditions, each silicon atom will form bonds with four...

An ordinary, neutral atom has an equal number of protons (in the nucleus) and electrons (surrounding the nucleus). Thus the positive and negative charges are balanced. Some atoms, however, lose or gain electrons in chemical reactions or in collisions with other particles. Ordinary atoms that ...
Fraser: So now what really defines an atom with being a certain kind of element? Why is hydrogen hydrogen and gold gold? Pamela: It’s all about the number of protons in the nucleus. If I have an atom and I strip every single electron out of the atom, I now have a very charged ...
The atom calculator is a tool for calculating the atomic number and the mass number based on numbers of atom components - protons, neutrons, and electrons (or vice versa). In addition, you can define the charge of ions with known numbers of protons and electrons. ...
MASS OF THE ATOM. The atomic mass increases with the increase ofZ. The mass of the atomic nucleus is approximately proportional to the mass number A—the total number of protons and neutrons in the nucleus. The mass of the electron (0.91 x 10−27g) is considerably less (approx-mately ...
