All the oxygen isotopes, natural or artificial, has 8 protons, because th atomic number of oxygen is 8.
Thorium, or Th, has an atomic number of 90. That means that every atom of thorium has 90 protons. The only naturally abundant isotope of thorium is 232Th, and so therefore it has 232 - 90 = 142 neutrons.
The relationship is that Y is the negative ion and X is the neutral atome of the same element. Particle X and particle Y are both atoms, and are of the same element as the number of protons (atomic number) is 9. With the same number of neutrons they are both the same isotope. Particle X is electrically neutral so is a neutral atom, particle Y has a single negative charge and is an anion. Inspecting the periodic table for aelement atomic number 9 the element is fluorine, the isotope is fluorine-19 (the only naturally occuring isotope of fluorine), X is a fluorine atom, Y is a fluoride ion.
Potassium have th atomic number of 19 this means it has 19 protons in its "core" and in atoms the number of electrons are always equal to the number of protons hence also 19. the number of neutrons however vary dependent on witch potassium isotope it is the average for potassium is however 20 in potassium 39
Any one element can ONLY have a single fixed number of protons. Th only element with a number of protons that sits between 50 and 75 in group 17 of the periodic table is Iodine (I), with 53 protons.
The isotope 234 Th.
All the oxygen isotopes, natural or artificial, has 8 protons, because th atomic number of oxygen is 8.
The atomic number of thorium is 90. So there are 90 protons and 90 electrons. In Th-230 isotope there are 140 neutrons (230 - 90 = 140) So there are 50 more neutrons than the number of protons.
For example a thorium isotope is Th-231 or 23190 Th.
they are the same element because an element has an atomic number through its number of protons so if there was an element with 2 protons it would be number 2 in the periodic table which is helium, if another element has 2 protons it should be helium still, if it wasn't modified in anyway
An example of beta decay for a thorium isotope: Th-231(beta)Pa-231.
Thorium, or Th, has an atomic number of 90. That means that every atom of thorium has 90 protons. The only naturally abundant isotope of thorium is 232Th, and so therefore it has 232 - 90 = 142 neutrons.
The top left number is the mass (neutrons&protons) and the bottom left number is the atomic number(protons)

The element with 45 protons is Rhodium which has the chemical symbol Rh. Rhodium is a transition metal in Group 9, Period 5 of the Periodic Table. Rhodium has 45 electrons in 5 shells with 1 electron in the outer shell.
