Find the number of protons and electrons of N-3.

Would it be 7protons, and 4electrons?
or 7 protons, and 7electrons?????

neutral Nitrogen has an atomic number of 7 (from periodic table) thus it has 7 protons and 7 electrons (equal +p and -e).

Since it is an ion with charge -3, it means that it gained 3 electrons. therefore, N^-3 has 7 protons and 10 electrons.

hope this helps~ :)

thank you!

To determine the number of protons and electrons in an ion, we need to know the atomic number and the charge of the ion.

The atomic number of nitrogen (N) is 7, which means it has 7 protons in its neutral, uncharged state.

In the case of N-3, the "-3" indicates a charge of -3. This implies that the ion has gained 3 electrons to have an overall charge of -3.

To find the number of electrons, we subtract the charge from the number of protons. In this case, it would be 7 protons - (-3 charge) = 7 + 3 = 10 electrons.

So, the correct answer is that N-3 has 7 protons and 10 electrons.

To determine the number of protons and electrons in an atom or ion, you need to know its atomic number. The atomic number of nitrogen (N) is 7, which means it has 7 protons.

In a neutral nitrogen atom, the number of protons is equal to the number of electrons. However, in the case of N-3, it indicates that nitrogen has a charge of -3. This means it has gained 3 extra electrons, making its electron count higher than the proton count.

To find the number of electrons, you subtract the charge from the atomic number. In this case, 7 - 3 = 4. Therefore, N-3 has 7 protons and 4 electrons.
