For the following nuclear reaction, what was the beginning radionuclide (X)? X → 86Rn222 + 2He4
BigorU [14]
The original radioisotope underwent double-alpha decay, where the original nucleus lost a total of 4 protons and 4 neutrons.

The original radioisotope would have an atomic number of 86+4 (protons), and would have an atomic mass of 222+8 (protons + neutrons). This would make the element Thorium-230, or 90Th230.

A system contains bonds between particles. Which choice describes the microscopic structures of the energy in this system? There
borishaifa [10]

Answer:

The correct answer is: <em>There must be potential energy in the bonds due to its particles position.</em>

Explanation:

Potential energy is a kind of energy which is stored in an object due to its position or configuration. For example, if there is a ball in the fifth floor of a building, it has a determined potential energy which is converted to kinetic energy when the ball fall down. The same is in the case of the chemical bonds: the particles or atoms have potential energy related to their relative positions in the system. In fact,  chemical energy is considered a form of potential energy (stored in chemical bonds).
