alpha particles.
The decay is: Th-230-------------Ra-226 + He-4
Thorium-230 has 30 more neutrons than electrons. Thorium-230 has 90 protons and 138 neutrons, while it has 90 electrons.
Thorium-230 has 90 electrons. This is because thorium has 90 protons, and the number of electrons in an atom is equal to the number of protons in order to maintain a neutral charge.
Thorium-230 decays into radium-226 through alpha decay.
Thorium-230 has 90 electrons because the number of electrons in an atom is equal to its atomic number, which is 90 for thorium.
Thorium-230 decays into radium-226 when it emits an alpha particle.
Thorium-230 and Thorium-234 are isotopes of thorium with different numbers of neutrons. Thorium-234 is typically found in higher abundance in nature compared to Thorium-230. Neither is inherently more dangerous than the other; their potential health effects depend on factors like exposure level and route of exposure.
The balanced nuclear equation for the alpha decay of thorium-230 is: ^230Th → ^226Ra + ^4He
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.
The atomic number of thorium is 90. so it will always have 90 protons in all its isotope.
Thorium has 90 protons. It does not matter which isotope is involved.
