Answer :
Final answer:
The charge of a singly ionized sodium atom (Na2+) is +2 and its mass is 22.989 u. The charge of the nucleus of a nitrogen atom (14N) is +14 and its mass is 14.007 u.
Explanation:
In the case of a singly ionized sodium atom (Na2+), the symbol 'iiNa' indicates that it has lost two electrons, resulting in a +2 charge. The mass of the sodium atom is given as 22.989 u.
For the nucleus of a nitrogen atom (14N), the symbol '14N' indicates that it has 14 protons, which gives it a +14 charge. The mass of the nitrogen nucleus is given as 14.007 u.
