Let's break down the information provided for the atom you described with 7 protons, 8 neutrons, and 10 electrons:
-
Is the atom neutral?
- Response: No, the atom is not neutral. An atom is considered neutral when the number of protons equals the number of electrons. In this case, there are 7 protons and 10 electrons, resulting in a negative charge.
-
Is the atom stable?
- Response: The stability of the atom mainly depends on the ratio of neutrons to protons and the presence of any isotopes. Generally, for lighter elements such as this one (with 7 protons), having more neutrons than protons (8 neutrons) can indicate some level of instability. However, since 7 protons correspond to nitrogen (atomic number 7), and 8 neutrons yield a nitrogen isotope (N-15), it is considered stable.
-
What is the atomic mass?
- Response: The atomic mass can be calculated by summing the number of protons and neutrons. Here, 7 protons + 8 neutrons = 15. Therefore, the atomic mass is approximately 15 atomic mass units (amu).
-
What is the atomic number?
- Response: The atomic number is defined by the number of protons in the nucleus. Here, with 7 protons, the atomic number is 7.
-
What is the atomic charge?
- Response: The atomic charge can be calculated by subtracting the number of electrons from the number of protons. Here, 7 protons - 10 electrons = -3. Therefore, the atomic charge is -3.
-
What is the atomic symbol?
- Response: The atomic symbol for nitrogen, which has an atomic number of 7, is N.
In summary:
- Neutral: No
- Stable: Mostly yes (N-15 is stable)
- Atomic Mass: 15 amu
- Atomic Number: 7
- Atomic Charge: -3
- Atomic Symbol: N
