Sodium nucleus consists of 11 protons and 12 neutrons. The conventional symbol of this nucleus is?
Correct answer: C. 11Na23
- A. 11Na11
- B. 12Na12
- C. 11Na23
- D. 12Na23
- E. 12Na11
Explanation
The conventional symbol of the element contains the proton number(number of protons) and the mass number(proton number+number of neutrons), which is 11 and (11+12=)23, in this case. So the correct option is C. The conventional symbol of a sodium nucleus is 11Na23.
