Neon has 10 protons and 10 electrons per atom. 20Ne is its most common isotope. It has 20 - 10 = 10 neutrons.
The atomic number of element X is determined by the number of protons, which is 7. For the second isotope, which has 10 neutrons, the mass number is the sum of protons and neutrons, calculated as 7 protons + 10 neutrons = 17. Therefore, the second isotope has an atomic number of 7 and a mass number of 17.
The element is Neon and the isotope is 10Ne19
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.
In-115 isotope has 66 neutrons
9 protons, 9 electrons and 10 neutrons in F-19 isotope.
Fluorine has an atomic number of 9. Therefore it has 9 protons and electrons. It has an atomic mass of 19 amu. Therefore, the number of neutrons present can be calculated by subtracting the number of protons from its mass, i.e., 19-9=10. thus, fluorine has 9 protons and 10 electrons.
Neon has 10 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a neon isotope = Mass number - 10
10 Protons 10 Neutrons in the most common isotope.
The element with 10 protons is neon (atomic number 10). Since the number of protons is equal to the number of electrons in a neutral atom, neon also has 10 electrons. With 12 neutrons, the isotope of neon described is neon-22.
Neon-22 has 10 protons, so it also has 10 electrons to balance the charge. To find the number of neutrons, subtract the number of protons (10) from the isotope's mass number (22). Therefore, Neon-22 has 12 neutrons.
