how many more neutrons does thorium-230 have then protons? how many electrons does thorium-230 have?
Follow my previous instructions.
#p + #n = mass number
#p = #e
To determine the number of neutrons, protons, and electrons in an atom, you need to understand the atomic structure of the atom.
Thorium-230 is an isotope of Thorium, having the atomic number 90. This means it has 90 protons. The atomic number represents the number of protons in the nucleus of an atom.
The mass number of Thorium-230 is 230, which represents the sum of protons and neutrons in the nucleus. To determine the number of neutrons, subtract the atomic number (protons) from the mass number. So, 230 - 90 = 140 neutrons.
Now, to find the number of electrons, we assume the atom is neutral, which means it has the same number of protons as electrons. In this case, Thorium-230 has 90 electrons.
In summary:
- Thorium-230 has 140 more neutrons than protons (90 protons and 140 neutrons).
- Thorium-230 also has 90 electrons, assuming it is neutral.
