The chemical symbol for fluorine isotope with 9 neutrons is 18F (18 is a superscript).
The isotope symbol for fluorine with 9 neutrons is ^18F, where 18 is the atomic mass number (protons + neutrons) and F is the chemical symbol for fluorine.
I think that's B, the symbol for the element boron. Boron has 5 protons and 5 electrons. The most common isotope has 6 neutrons. The other main isotope has only 5 neutrons.

Antimony (symbol Sb) has three isotopes: 121Sb, 123Sb, and 125Sb. The 121 isotope has 70 neutrons, and the 123 isotope has 72 neutrons. The 125 isotope isn't stable and will decay, but it has 74 neutrons.
The correct nuclear symbol for an isotope with 80 protons and 124 neutrons is Xe-204, where Xe represents the element xenon.
The chemical symbol for fluorine isotope with 9 neutrons is 18F (18 is a superscript).
The isotope symbol of plutonium with 146 neutrons is plutonium-246, represented as ^246Pu.
The isotope symbol for fluorine with 9 neutrons is ^18F, where 18 is the atomic mass number (protons + neutrons) and F is the chemical symbol for fluorine.
The isotope with 15 protons and 17 neutrons is Phosphorus-32, which has a symbol of P-32.
I think that's B, the symbol for the element boron. Boron has 5 protons and 5 electrons. The most common isotope has 6 neutrons. The other main isotope has only 5 neutrons.
Polonium (symbol, Po) is an element with 84 protons and 84 electrons. In Po-185 isotope, there are 101 neutrons.
Sulfur is a chemical element with the symbol S and atomic number 16. It has 16 protons, 16 neutrons and 16 electrons.
The symbol for a sodium isotope with 12 neutrons would be "Na-23". This notation indicates the element symbol "Na" for sodium and the total number of protons and neutrons in the nucleus (12 neutrons + 11 protons = atomic mass number 23).

There are a variety of isotopes that have 30 neutrons. It isn't the number of neutrons that determines an element, but the number of protons. Electrons generally balance the number of protons.
