Any element with 7 protons would be Nitrogen
The element with 7 electrons, 7 protons, and 8 neutrons is nitrogen-15 (15N).
A positively charged ion of oxygen
Elements are determined by their number of protons. Nitrogen has 7 protons but usually 7 neutrons as well. What you have here is a nitrogen isotope, an element with more or less neutrons than there are protons. Specifically, this is Nitrogen-15.
The element that has 9 protons is fluorine. Its atomic number is 9, indicating that the element has 9 protons in the nuclei of its atoms. If there are 10 electrons, then the fluorine atom has gained an electron and is now a negatively charged anion with a charge of 1-.
The element with 8 protons is oxygen (symbol O). It normally has 8 electrons as well, but in this case it has one extra electron, making it an ion. With 7 neutrons, the ion is known as oxygen-15.
7 protons 7 electrons 8 neutrons
An atom containing 7 protons, 8 neutrons, and 7 electrons is a neutral isotope of nitrogen, specifically nitrogen-15 (N-15). The number of protons defines the element as nitrogen, while the number of neutrons contributes to its atomic mass, giving it a total of 15 (7 protons + 8 neutrons). The identical number of electrons ensures that the atom has no overall charge.

The element with 8 protons and 8 electrons is oxygen (O). The presence of 11 neutrons indicates a specific isotope of oxygen, oxygen-19.
There are 7 protrons, 7 electrons and 7 electrons in an atom of nitrogen.
Nitrogen-14 has 7 protons, 7 electrons, and 7 neutrons. Nitrogen-15 has 7 protons, 7 electrons and 8 neutrons. So, the only way they differ is in the NUMBER OF NEUTRONS.
I'm pretty sure its Sulfur...
