Radium
Radium - 228.
The nuclear reaction is: 232Th--------------- 228Ra + α
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
Thorium 230 has 90 protons and 140 neutrons - the difference is 50.
No, when a neutral atom gains or loses electrons, its number of protons does not change. The number of protons in an atom determines its atomic number and identity as a specific element. Gaining electrons results in a negatively charged ion (anion), while losing electrons creates a positively charged ion (cation). However, the atomic structure and the element remain the same.

Well what element are you starting out with?
the number of protons in an atom is what determines which element the atom is. So if an atom "lost" a proton, it would become another element entirely.
Thorium's atomic number is 90. Thus, thorium has 90 protons per atom. To be electrically neutral then, thorium must also have 90 electrons per atom.
Thorium is a metal element. There are 90 electrons in a single atom.
Thorium (Th).
An ions is formed when an atom gains or loses electrons.
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
Thorium 230 has 90 protons and 140 neutrons - the difference is 50.
