Hint: As we know that protons are positively charged, electrons are negatively charged. If we have to find the number of neutrons, we will subtract the atomic number from the mass number. And we can easily find the electrons, neutrons and protons.

Complete Solution :
- As we know that nitrogen - 14 is mainly an isotope of nitrogen. And we can say that it is a neutral atom. And isotopes generally have different numbers of neutrons and the same number of protons.
- As we all know that atomic number denotes the total number of protons present in the nucleus of an atom. As we are provided with the information that the mass number of nitrogen is 14, and we know that the atomic number of aluminium is 7.
- It is found that the number of protons is equal to the atomic number. This clearly means that any atom which is an isotope of aluminium will basically have 7 protons in the nucleus.
- And the number of electrons is equal to the proton number. Hence, we can say that there will be 7 electrons.
- Now, we will calculate the number of neutrons present. As we know that mass number= number of protons + number of neutrons. Hence, the number of neutrons will be = 14 - 7 = 7.
- Hence, we can conclude that there are 7 electrons, 7 protons, and 7 neutrons that nitrogen-14 have and it isn’t an anion or cation. It is a neutral atom.

Note: - We should note that the total number of neutrons present in the nucleus is equal to the difference between the atomic number and the mass number of an atom.
- As we know that the mass number of any atom is basically equal to the addition of the protons and neutrons that are present in the nucleus.
