Neon
Neon has 10 protons and 9 neutrons.
The element is Neon and the isotope is 10Ne19
10 Protons 10 Neutrons in the most common isotope.
Any atom, ion, or isotope with 12 protons is going to be magnesium. Only the number of protons in the nucleus will determine the element. But with the information about the number of neutrons, the specific isotope can also be determined - 22Mg.
The element neon has 10 protons as its atomic number is 10.
Fluorine. Number in periodic system = Number of protons
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 is Neon and the isotope is 10Ne19
The number of protons gives the element number; element number 9 is Fluorine.
The element that has 8 protons and 8 neutrons is oxygen.
The nuclear symbol for an element with 9 protons and 10 neutrons is 19F. The atomic number (number of protons) is shown as a subscript to the left of the element symbol, and the mass number (sum of protons and neutrons) is shown as a superscript to the left of the element symbol.
none because the number of protons and electrons have to be the same.
