Answer 1

To determine the composition of a nitrogen ion with a mass of 14 and a charge of +2, let's first analyze the information:

1. The atomic number of nitrogen is 7, which means a neutral nitrogen atom has 7 protons.
2. Since the ion has a charge of +2, this means it has lost 2 electrons. A neutral nitrogen atom has 7 electrons, so this ion will have: \[ 7 \text{ electrons} - 2 = 5 \text{ electrons} \]
3. The mass number is given as 14. The mass number is the sum of protons and neutrons. For our nitrogen ion: \[ \text{Mass Number} = \text{Number of Protons} + \text{Number of Neutrons} \] We know there are 7 protons (from the atomic number of nitrogen): \[ 14 = 7 + \text{Number of Neutrons} \] This means: \[ \text{Number of Neutrons} = 14 - 7 = 7 \]

Now, we can summarize the subatomic particles in the nitrogen ion:

• Protons: 7
• Neutrons: 7
• Electrons: 5

Thus, the correct answer is: 7 protons, 7 neutrons, and 5 electrons.
