What are the charge and mass of the following?

a) A singly ionized sodium atom (Na⁺).
- Charge: [Specify charge in terms of elementary charge, e.g., +1e]
- Mass: 22.989 u

b) The nucleus of a nitrogen atom (¹⁴N).
- Charge: [Specify charge in terms of elementary charge, e.g., +7e]
- Mass: 14.007 u

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.
