Question

Розрахуйте склад атомних ядер таких ізотопів:
а) 12 C і 13 C;
б) 14 N і 15 N;
в) 28 Si і 30 Si?

Answer 1

Ответ:a) 12 c and 13 C are carbon isotopes that have the same proton number 2 = 6, but differ in the nucleon number A. The 12 C nucleus has 6 protons and 6 neutrons, and the 13 C nucleus has 6 protons and 7 neutrons 12

6) 14 N and 15 are nitrogen isotopes that have the same proton number 2 = 7, but differ in the nucleon number A. The nucleus of 14 N has 7 protons and 7 neutrons, and the nucleus of 15 N has 7 protons and 8 neutrons

Объяснение:...

c) 28 Si and 30 Si are isotopes of silicon that have the same proton number 2 = 14, but differ in the nucleon number A. The nucleus of 28 Si has 14 protons and 14 neutrons, and the nucleus of 30 Si has 14 protons and 16 neutrons
