例句與造句

1. In beta decay, the proton number increases by one.
2. Nuclides that have the same neutron number but a different proton number are called isotones.
3. Still other possible beryllium isotopes have even more severe mismatches in neutron and proton number, and thus are even less stable.
4. Because positron emission decreases proton number relative to neutron number, positron decay happens typically in large " proton-rich " radionuclides.
5. Nickel is to the right of cobalt, since its proton number ( 28 ) is higher by one than that of cobalt ( 27 ).
6. It's difficult to find proton numbers in a sentence. 用proton numbers造句挺難的
7. A filled shell would have " doubly magic " ( both its proton number of 114 and neutron number of 184 are thought to be magic ).
8. Chemical properties are primarily determined by proton number, which determines which chemical element the nuclide is a member of; neutron number has only a slight influence.
9. Under conditions encountered in astrophysical environments it is difficult to obtain p-nuclei through proton captures because the Coulomb barrier of a nucleus increases with increasing Proton number.
10. Rutherford realised that if an atom is losing protons, its identity is changing at the same time, since an atom s identity is governed by its proton number.
11. This placement is consistent with the modern practice of ordering the elements by proton number, " Z ", but that number was not known or suspected at the time.
12. Nuclear isomers are members of a set of nuclides with equal proton number and equal mass number ( thus making them by definition the same isotope ), but different states of excitation.
13. For a positron decay and also for an alpha decay ( see below ), the oblique arrow would go from right to left since in these cases, the proton number decreases.
14. Although its proton number of 58 is not magic, it is granted additional stability, as its eight additional protons past the magic number 50 enter and complete the 1 g 7 / 2 proton orbital.
15. It is useful to think of the decay scheme as placed in a coordinate system, where the ordinate axis is energy, increasing from bottom to top, and the abscissa is the proton number, increasing from left to right.
16. But with that exception, all elements with proton numbers greater than the 92 of uranium must be made in laboratories, and with Element 114, 21 artificial elements have been made . ( Element 113 is missing from the sequence .)
