Complete the missing information in the chart. Assume these are neutral atoms.
Element symbol __ Atomic number 7 Mass number 14 Number of protons __ number of neutrons. __ number of electrons __

Answer 1

To complete the chart for the given neutral atom, we'll use the provided information:

1. **Element Symbol**: The element with atomic number 7 is nitrogen (N).
2. **Atomic Number**: You have provided this as 7.
3. **Mass Number**: You have provided this as 14.
4. **Number of Protons**: In a neutral atom, the number of protons equals the atomic number, which is 7.
5. **Number of Neutrons**: The number of neutrons can be calculated using the formula:
\[
\text{Number of Neutrons} = \text{Mass Number} - \text{Number of Protons}
\]
Substituting the values:
\[
\text{Number of Neutrons} = 14 - 7 = 7
\]
6. **Number of Electrons**: In a neutral atom, the number of electrons equals the number of protons, which is also 7.

Now, we can fill in the missing information:

- **Element Symbol**: N
- **Atomic Number**: 7
- **Mass Number**: 14
- **Number of Protons**: 7
- **Number of Neutrons**: 7
- **Number of Electrons**: 7

Here's the completed information:

- Element Symbol: N
- Atomic Number: 7
- Mass Number: 14
- Number of Protons: 7
- Number of Neutrons: 7
- Number of Electrons: 7
