 * 1) Now, we must admit that, the term “atom” is wrong name, because we know, that the atom consists of a positive nucleus and a number of negative electrons moving around it.
 * 2) Hear are a few words, which should be set to encourage the scientist in his endeavour to examine the structure of the neutron.
 * 3) The difficulties we encounter with could be avoided if we did not explore the structure of elementary particles.
 * 4) Once/if we were confronted with these errors, let us demonstrate the true state of things
 * 5) They are unlikely to fulfill this work in time.
 * 6) It would be better if you did not pay much attention to these tiny facts.
 * 7) However, it is unlikely that this consideration will be accepted as a replacement of experimental proof.
 * 8) This field of physics encompasses a number of unexplored phenomena.
 * 9) What are fundamental parts of this matter?

Properties of the electron. Pauli’s exclusion principle.
 * 1) We have spoken so fare about an electron and its properties.
 * 2) In order to explain spectral lines in accordance with quantum theory, the scientists had to postulate the spin.
 * 3) Though they are twins, but there are a number of properties that help us to tell them apart/tell one from another. For example, fingerprints.
 * 4) In every day life there are no two individuals absolutely alike.
 * 5) Apart from incorporating elementary charge, it also represents an elementary magnetic dipole.
 * 6) The spin influences magnetic behavior of the electron.
 * 7) Within the errors of measurement your experiment can be considered successful.
 * 8) In the area of elementary particles a new measurement could prove the only true.
 * 9) Apparently, unavoidable errors of measurements will lead to more ambiguity of final results.

1. 2. The only interaction between electrons, which must be discussed, is the electrostatic repulsion, determined by a charge of electrons. 3. According to Pauli’s Exclusion Principle, we shall never find to electrons of the same sing spin in the same orbit of an atom. 4.
