Question
Deduce from the datum provided.
| Datum | To deduce |
| \[\ce{_11^23Na}\] | Neutron number |
| \[\ce{_6^14C}\] | Mass number |
| \[\ce{_17^37 Cl}\] | Proton number |
Solution
| Datum | To deduce |
| \[\ce{_11^23Na}\] | Neutron number = Mass number - Number of protons = 23 − 11 = 12 |
| \[\ce{_6^14C}\] | Mass number = 14 |
| \[\ce{_17^37 Cl}\] | Proton number = Atomic number = 17 |
